ARS4-C / User Manual ADC GmbH User Manual for 76 - 77 GHz Adaptive Radar Sensor ARS4-C page 1/5 Copyright © by Continental 2019 All rights reserved
ARS4-C / User Manual ADC GmbH 1. Purpose In this document an operational description of Continental´s 77 GHz Advanced Radar Sensor ARS4-C is given. Sufficient information is provided to understand the operation principle, the set up and the tuning of the radar sensor.
ADC GmbH ARS4-C / User Manual 2. General information The ARS4-C sensor measures independently the distance and velocity (Doppler's principle) to objects without reflector in one measuring cycle on the basis of FMCW (Frequency Modulated Continuous Wave) with very fast ramps. A special feature of the device is the simultaneous measurement of large distances up to 250 meters, relative velocities between ±300 km/h and the angle relation between two objects.
ARS4-C / User Manual ADC GmbH 3. ARS4-C Sensor Component Description The ARS4-C sensor consists of the following components: Plastic housing with sensor Data Interface connector Radio Frequency (RF) Printed Wiring Board (PCB) including the antenna which is plugged into the housing Low Frequency (LF) PWB incl. Board-to-Board (B2B) Connector (connector between RF and LF unit) A plastic molded radome through which the radar beams are emitted.
ARS4-C / User Manual ADC GmbH 4. ARS4-C Sensor Software Operation Several operational modes based on vehicle speed exist where the sensor measures continuously with pulse frequency modulation (FM). The sensor operates in this mode over its life time in the vehicle, being powered by the vehicle power supply.
