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 GH z.

The 24 GHz Short Range Radar platform is based on UWB technology using a proprietary freque ncy 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 sign al 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 (Mid Range Range): 0.2 – 65m ±8° detection zone
SRR (Short Range Radar) Front: 0.2 – 30m ±40° detection zone
SRR (Short Range Radar) Side: 0.2 – 10m ±40° detection zone
MMR (Multi Mode Radar): 0.2 – 30m ±40° detection zone

0.2 – 65m ±8° detection zone
SQ (Multi Mode Radar): 0.2 – 30m ±40° detection zone

0.2 – 65m ±8° 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.
