1 General Description
Autoliv manufactures different types of 24 GHz Short Range Radar sensors. The sensor types are working in two
modes, NB (Narrowband) mode and UWB (Ultra Wide Band) mode. In the NB mode the sensor is working in the
frequency band 24.25-24.25 GHz, in the UWB mode in the frequency band 24.25-26.65 GHz.
The 24 GHz Short Range Radar platform is based on UWB technology using a proprietary frequency hopped,
pulsed, coded FMCW like waveform. This advanced waveform enables very high resolution to be achieved in both
range and Doppler. The fast signal processing allows very low latency and fast radar cycle times, a prerequisite for
highly dynamic driving characteristics. The waveform is scalable in software.
The sensors are used for automotive applications for both side looking and forward/back looking applications.
Examples are warning and braking functions to improve the safety on the road.
The 24 GHz radar platform covers variants which differ in their individual waveform and signal processing.
Depending on the application (front or side or rear) the variants cover a specific detection range (short range or mid
range) and detection zone.

MRR sensors are used for medium range applications such as forward collision warning. SRR sensors are used for
short range applications such as Stop&Go or blind spot monitoring.
MMR & SQ sensors have combined SRR and MRR functionality and are designed to function in both a short range
and a longer range.
The 24 GHz SQ sensor is an advanced development of the 24 GHz MMR sensor. The technical specification for
the 24 GHz SQ sensor remain the same.

1 Sensor Description
1.1 Sensor Components
The sensor consists of five main mechanical components (Housing, DSP Board, Shielding, RF Board, Radome).
Sensor Components
The connector header is part of the sensor plastic housing. Two connector options are possible.

1.2 Sensor Dimensions
The assembly process is in an advanced robot based production process. The size and light weight of approx.140
grams reduce the complexity of integration across a wide range of vehicle platforms.

1.3 Sensing Characteristics
The specification for SRR (Short Range Radar) and MRR (Mid Range Radar) are different due to a different range
of detection and field of view. The MMR (Multi Mode Radar) is a combination of SRR and MRR. The SQ sensor is
an advanced version of the MMR sensor.

2 Radar Waveform Description for Mitigation
Autoliv has developed a proprietary frequency hopped, pulsed, coded FMCW like waveform. The radar codes
transmit information in time and frequency and separates return information in both the doppler domain and
distance domain. A target return can be separated from a target return of another transmitter station in three ways.
1. During the frequency dwell segment of the waveform (very short, approx. 6us) the waveform is transmitted
with a coded pulse waveform. The receiver gate is only open for specific time slots. These two combine to
reduce the effect of interfering "on frequency" transmitters.
2. The waveform sweeps over a very wide bandwidth in a short period of time (1GHz in 20ms). The IF
bandwidth is very small (less than approx.. 1MHz) thus the rejection of interfering stations is very high as it
is related to the ratio of the spread bandwidth and the IF bandwidth.
3. The transmit waveform is a random frequency hop (actually a coded frequency). Thus any interfering
stations can be distinguished from the required transmitter as they do not transmit in the same coded
frequency space.
The randomness of the pulse waveform and the frequency hopping results in the overall effect that interferers are
mitigated and are suppressed to behave as noise like signals in the receiver chain. This mitigates the deleterious
effects on the signal processing chain.

4 Vehicle Integration
Autoliv has experienced with body mounted and fascia mounted attachment. Preferably, the sensor slides in a
plastic bracket attached onto the fascia as represented below:
The packaging guidelines have proven to be effective in use at several OEM’s in series production using AUTOLIV
radars. Highlights of the guidelines:
•
•
•
Keep out zone in front of sensor
No metal parts (screws, license plates, clips, etc), impact absorbing foam, fascia creases) inside +/- 65 deg
azimuth, +/- 30 deg elevation
Sensor spacing from fascia 5mm to 20 mm

Directive 1999/5/EC of the European Parliament on radio equipment and telecommunications terminal equipment
(R&TTE Directive).
The 24 GHz radar sensor complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1)
this device may not cause harmful interference, and
(2)
this device must accept any interference received, including interference that may cause undesired
operation.
The 24 GHz radar sensor complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to
