6.5. Validation
In order to evaluate the general performances of the installation, the best way to
proceed is to send people walk over the coverage of the radar.
Following this evaluation, two types of setting can be performed:
- Update the equipment and their installation properties (see § 6.5.1)
- Update the zones, (see § 6.5.2)
6.5.1. Equipment and installation properties update
The camera and radar installation properties can be updated through the « System
Management -> Equipment Configuration » menu.
Figure 141 Equipment installation properties update
Radar installation properties update:
- Solution#1
o Disconnect from the radar to be updated (PU), update the radar
installation properties and re-connect to it. The PSR-500 Installer will
automatically detect a discrepancy between the current version of the
System Configuration of the PSR-500 Installer and what the radar is
aware of. The application proposes either to apply the modification to

6.5.2. Zone update
In Installation mode, through the System Management -> Zone Definition menu, you
Figure 143 Zones update
Please note that each zone modification performed in the PSR-500 Installer will not
be known by the Radar(s) until you update their own configuration.
Therefore, you have two possibilities:
- Solution #1
- Disconnect all the radars to be updated from the PSR-500 Installer
- update zones properties through the PSR-500 Installer
- Click on System Management -> Equipment Global Management ->
Update All Radar PU(s). The application re-connects to all the radars
and updates them with the new system configuration.

- Solution #2
PSR-500 System Installation Guide
Page 104 / 125
CPN 222-3044-657 Rev B CAGEC F5491 Rockwell Collins - Proprietary Information
o Do not disconnect radars from the PSR-500 Installer
o Update zones properties through the PSR-500 Installer
o Radar by radar, extend the network configuration window of the radar,
and click on « send to PU » to apply the update to the PU.
Each time you change zones sensibility, keep in mind the induced effect.
The best performances of the PSR are achieved in « normal » sensibility.
« Normal » sensibility is the best trade-off between detection probability and
false alarm rate (min 0.35m/s and 4s before triggering the alert)
« High » sensibility mode will lead the radar to be more reactive on very low
radial velocity motion (min 0.2m/s) and faster to trigger alerts (2s) but will also
lead the radar to be more subject to false alarm due to animals or moving
trees.
« Low » sensibility mode will lead the radar to be less sensitive to spurious
activity (animals, moving trees) (min 1m/s and 4s before triggering the alert)
but will also lead the radar to be much less sensitive to low radial velocity
targets.
« User defined » sensibility mode gives you access to more properties
(available in Help -> Advanced mode only (no password required) ) (min
0.05m/s and 1s before triggering the alert)
6.5.3. End of the validation phase

System performances optimization is linked with the radar technology concepts,
which were detailed in previous sections of this document.
8.1. Detection capability
8.1.1. Reactivity
The PSR-500 radar maximum reactivity time to trigger an alert (linked to an intrusion)
is 4 seconds.
This performance is achieved if the following conditions are fulfilled:
- The intruder shall be in the detection area covered by the radar
- The intruder shall not be hidden by any obstacles between the radar and him. If
the intruder is partially hidden, then the performances of the radar will be
decreased.
-
account radar location and features of the detection area.
If one of the previous conditions is not fulfilled, then the performances in terms of
reactivity and detection range will be decreased. In this case, radar installation
optimization is required to fulfill these conditions (as detailed in previous sections of
the document).
ind that this reactivity can be localy improved
through tuning of detection zones features.
8.1.2. Localization accuracy
Alert localization accuracy for each radar is directly linked to the quality of the
intruder detection.
The better the detection will be, the most accurate will be the localization accuracy.
As explained before in this document, the localization accuracy is linked to :
- The proximity between the intruder and the radar
- The proximity between the intruder and the boresight of the radar
- No masking area, even partial, between the intruder and the radar
These aspects have to be taken into account when the operating zones are created
(detection or exclusion).
At the edge of the detection range (500m), the test results in a clean environment
(flat zone with pedestrian perfectly visible) show that each radar can localize an
intruder with the following performances:
- Range accuracy: worst case +/-5m whatever the distance between the
intruder and the radar
- Angular accuracy: worst case +/-15m @500m (i.e.: +/-
bear in mind that this accuracy gets better as the intruder comes closer to the
radar.

CPN 222-3044-657 Rev B CAGEC F5491 Rockwell Collins - Proprietary Information
8.1.3. Effect of the outside temperature
Outside temperature has a direct effect on the detection performances of a radar.
The colder it will be, the more sensitive the radar will be. Indeed, when the outside
temperature increases, the internal noise of the radar reception chains increases as
well and the efficiency of the amplifiers decreases. Thus the impact of this
phenomenon is a reduction of the radar sensitivity.
As a conclusion, outside temperature has a direct effect on the reactivity and the
localization accuracy of the radar.
8.2. False alarm
The performances of an « active » surveillance sensor are defined by its detection
rate and its false alarm rate.
Each radar of PSR-500 system is preset to reach optimum performances, i.e.: to
ensure the best trade-off between detection sensitivity and false alarm.
Nevertheless, radar system performances can vary depending on the environment
ployed:
-
- Vegetation (
-
- Seasons and meteorological conditions (temperature, humidity
The performances of each radar have to be monitored for each deployment and also
in operation.
Indeed, the real value of a radar false alarm rate can not be calculated in a very short
time. Usually the false alarm rate of a radar is defined by the number of false alarms
per hour or per day of operation. In order to validate that the false alarm rate is in line
with customer expectation, the radar will have to operate during several days.
Various meteorological conditions are necessary during the observation period of the
radar in order to optimize the performances. For instance, it could be useful to focus
on days where the weather conditions were bad.
Performances optimization will need to investigate non-detections or potential false
alarms and system configuration update could be performed as weel (i.e. : features
of operating zones).
not without visual confirmation. If the operator is not there during the false alarm
analysis phase, then access to recorded video stream from cameras (installed on the
site) will be mandatory for visual check and doubt removal.

value, i.e. : « Statuts + Radar data (Alarms + Pre-alarms) ».
WARNING : minimum hard disk space is required when observation period is
activated.
In average,
The recorded data from a radar when the observation period activated is
around 15Mo/day in average. The size of the memory will depend on the activity
observed in front of the radar.
The graph below shows an example of hard disk memory space used on a site
where 7 radars were deployed and in operation during 8 days:
PSR-500 System Installation Guide

CPN 222-3044-657 Rev B CAGEC F5491 Rockwell Collins - Proprietary Information
Figure 147 Memory register analysis
When the observation period is activated, the system shall operate during at least
24h.
8.4. Investigation
As previously explained, when the observation period is activated, the PSR-500
Server continuously records detailed information of all the alerts observed by each
radar.
The PSR-500 Investigator will allow to go through all the registers of each radar and
retrieve relevant information by :
- Displaying the list of recorded alarms
- Showing on the site map the movement of the intrusion alerts.
To use the recorded data by the PSR-500 Server, some files transfer will have to be
performed in the PSR-500 Investigator.
To do so :
- Copy/Paste the system configuration folder from repository
/PSR_System_Configuration of the PSR-500 Server (or PSR-500 Installer)
to the repository /PSR_System_Configuration of the PSR-500 Investigator

8.4.3. Accumulation of observed activity on one day
Log analyser has advance feature, which allows to accumulate observed activity for a
a dedicated radar for a specific day (corresponding to the file loaded).
This function will go through the map and count during the selected day the number
of alerts per pixel on the map.
As a result, the function will display an accumulation of alerts, which will be used to
assess the density of alerts per zone.
Furthermore, this function is very useful to identify areas with a lot of spurious alarms
used in operation to update exclusion zones in order to reduce the false alarms rate
close to these zones.
- To display this accumulation map, click on « Activity Map » button. This action
requires some time, as the PSR-500 Investigator application has to go
through all the recorded data of the selected file:

8.5. False alarm mitigation
False alarm mitigation consists in changing some system installation parameters to
reduce the false alarm rate. This installation parameters change will be performed
with PSR-500 Installer application thankd to the method described in section 6.5.
As explained in this section, the most common way to mitigate the false alarms is to
adjust the drawing of the surveillance zones (warninig, caution, exclusion) in order to
erase zones with high density of false alarms.
sensitivity of the detection zones, which are configured in the system.
When the system configuration is changed via the PSR-500 Installer, if the PSR-500
Server (master and/or slave) is connected to the radars, then the server will
automatically see the changes on each radar. Without any action from the user, the
system configuration known by the PSR-500 Server will be automatically updated in
the PSR-500 Server. The last action will consist in connecting to the server machine
to amnually save the system configuration via the menu System Management ->
System Configuration -> Save. Then, in case of restart, the PSR-500 Server wille be
launched with the last system configuration version.
8.6. Mitigation validation
Mitigation validation will consist in performing the previous investigation step in order
to ensure that the PSR-500 false alarm rate is compliant with customer expectations.
Note changes after several months or years,
Thus the PSR-500 system false alarm rate will have to be carefully monitored over
the time.

9.1. Display of the radar covering area
After creation of a new system configuration and in particular the addition of a new
radar with the PSR-500 Installer, the shape of the radar covering area shall be
displayed as below:
Figure 161 Nominal shape of the PSR-500 radar covering area
If the shape is different, then the final performances of the PSR-500 system will
be impacted.
The map referencing was not correctly performed. Perhaps the geographical
localization was inverted (latitude/longitude) or the coma was not well placed. In this
case, the creation of the system configuration shall be performed again, starting from
the beginning.
Indeed, the map referencing and its accuracy are the key points to ensure system
performances.
9.2. Control the status of the deployed radars
Each radar of the PSR-500 system is monitored by maintenance network
components (if they are deployed, configured and tested as explained in this guide)
through the « master » PSR-500 Server.
In case of abnormal operation, the automatic maintenance is launched.
Nevertheless, it may occur operational scenario where the automatic maintenance
can not solve the problem.
Be carreful, if an operator needs to perform a maintenance operation of a radar, the
PSR-500 Server (master and slave) shall be disconnected from this radar to avoid

that the automatic maintenance takes the control of the associated network
equipments during the maintenance operation.
In any case (automatic maintenance or not), it is needed that the operator is able to
control the deployed radars and to diagnose an eventual failure.
Within the PSR-500 Installer, PSR-500 Viewer or PSR-500 Server applications, the
