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 (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.

Sensor Components The connector header is part of the sensor plastic housing. Two connector options are possible. • 1x6 Hirschman (shown) • 1x8 USCAR 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. File Name: 24 GHz SQ_Technical Description_Installation Guide Date: 31. July 2013 Autoliv Document, DUPLICATION or DISCLOSURE PROHIBITED without prior written consent 5 (9) 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. 65m 30m Short Range Field of View SR FOV Mid Range Field of View MR FOV Detection Zone for SRR and MRR File Name: 24 GHz SQ_Technical Description_Installation Guide Date: 31.

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. File Name: 24 GHz SQ_Technical Description_Installation Guide Date: 31.
