1. GENERAL DESCRIPTION
1.1 SCOPE
This chapter provides general description of the ELM-2127 system and its main components.
1.2 INTRODUCTION
The Smart Miniature Detection Radar (ELM-2127) is small ground surveillance radar used for anti-
intruder operations. It detects and tracks the intruder movements in and out of any fenced area
(Figure 1-1 and Figure 1-2) or selected zone such as: borders (terrorism, drug smuggling etc.), army
bases, power stations, prisons, mines, governmental buildings, nuclear facilities, airports, oil
reservoirs.
The ELM-2127 is tailored to the customer site type, terrain constraints, environmental conditions, type
of threats to guard from, nature of law enforcement roles and concept and many other parameters.
The ELM-2127 utilizes an advanced waveform with signal processing techniques for high resolution
and high probability of target detection, coupled with low radiated power.
The ELM-2127 low power consumption, small volume, and full solid state design enables deployment
in almost any area, terrain and weather conditions, while featuring high Mean Time between Failures
(MTBF).
The ELM-2127 is comprised of an RF transceiver module, digital receiver and signal processor,
antenna modules, and DC-DC converter.
Detected targets are displayed on a separate PC display. The radar display may be deployed at large
distance from the system via LAN or wireless network.
The ELM-2127 power is supplied by an external 24 VDC power source, converted internally to the
required power supply.

1.3 ELM-2127 MAIN FEATURES
High resolution pulse-Doppler radar operating in the upper X- frequency band.
Consists of two printed-patch array mono-pulse antennas. No moving parts; target area is
scanned using phased array techniques.
The phased array antennas divide the coverage area into discrete, smaller sectors. Each
antenna covers ±30° in azimuth providing overall coverage of 120° in azimuth and 10° in
elevation.
Low power dissipation.
Provides automatic detection and tracking for the alert phase. The system alerts that a
movement is detected and indicates the alert on a map.
Built in a compact case that may be installed on any building, fence, or tower and is easily
transportable (by light vehicle or carried by a single person).
Enables operation as stand-alone by local operator in a fixed installation or portable.
Enables integration with other systems via Ethernet or WLAN to a host system.
Operates in bad weather conditions. ELM-2127 performs well under adverse weather conditions:
rain, fog, high and low temperature extremes.
Classifies the detected target. Classification is usually done without operator assistance.

1.4 SYSTEM ARCHITECTURE
The ELM-2127 system consists of the following subunits:
Multiple ELM-2127 sensors - connected to operator computer (tactical center) or other systems
using Ethernet.
Operator indoor or outdoor post - based on PC or laptop computer with dedicated ELM-2127
application, providing ELM-2127 Human Machine Interface (HMI).
Remote Command & Control (C&C) interface via Ethernet communication.
NOTE
In the current application, only one sensor is connecter to
each tactical center.

1.4.1 ELM-2127 Sensor
The ELM-2127 is composed of one or more sensors (Figure 1-4), connected using Ethernet to
operator post.
The ELM-2127 sensor consists of the following:
A/D Timing (A1) module - includes two main sections:
− Digital receiver - performs A/D conversion and digital reception.
− Single Board Computer - performs signal processing, communication with the tactical center
via Ethernet and sensor timing and control.
Two Antenna modules (A3, A4) - perform RF signal transmission and reception using phased
array technology. Each antenna provides sigma and delta channels for reception.
RF Transceiver module (A2) - generates RF signal for transmission, and during reception, down
converts RF signals to IF and sends them to A/D Timing module.
Power conversion module - DC to DC converters, which converts 24 VDC input power to power
supplies for sensor models.

CHAPTER 2
DEPLOYMENT
2.1 SCOPE
This chapter details ELM-2127 system preparation for use, including deployment and installation.
2.2 SENSOR LOCATION SELECTION
The ELM-2127 sensor is located at a point from which there is a free line of sight from the radar to
the entire transmission area around the radar. Verify ELM-2127 sensor is positioned as far as
possible from fixed or mobile radio emitting equipment such as communication sets of any type or
other radars.
The ELM-2127 sensor is should not be deployed near high power electrical cables. Verify that no
high power electrical cables are located within 30 m around the sensor or 10 m above the sensor.
Operator post can be located at a remote location or close to the ELM-2127 sensor.
NOTE: This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense.
ELM-2127 sensor emits electromagnetic radiation. Verify no personnel are located
within the danger area of 1m from the front sector of the sensor and 0.5m from the rea
r
sector of the sensor (Figure 2-1). To comply with FCC RF exposure requirements, this
radar must be installed to provide a separation distance of at least 2 meters from all
persons. See FCC ID and Warning Label on the top access cover of the radar.

2.3 ELM-2127 DEPLOYMENT
2.3.1 Unpacking ELM-2127 Sensor
To unpack ELM-2127 sensor, proceed as follows:
ELM-2127 sensor radome is sensitive to mechanical
damage. While moving the ELM-2127 sensor, verify
radome does not come in contact with sharp or abrasive
objects. Do not rest the ELM-2127 sensor with the
radome facing down, on the radome corners or edges.
Failure to comply may cause damage to ELM-2127
sensor radome.
1) Verify ELM-2127 storage box [1] is intact and without any visible damage.
2) Release ELM-2127 storage box locking strips [2] and open the box.
3) Using ELM-2127 sensor carrying handles, carefully remove ELM-2127 sensor (3) from the
storage box.
4) Visually inspect ELM-2127 sensor and verify its exterior is intact and clear of dust or dirt. If
required, clean it using soft dry cloth.
