The ARS4-A is a 77 GHz radar sensor offering simultaneous long and short range detection
The Continental ARS4-A Radar is designed for forward collision warning, emergency brake assist, collision mitigation system or Adaptive Cruise Control (ACC). A special feature of the device is the simultaneous measurement of long distances, up to 250m with +/-0.2m accuracy, and short range, up to 70m, relative velocity and angle between two objects. It is thus able to detect stationary objects without any camera support.
The system integrates two electronic boards including an NXP Semiconductor microcontroller and Broadcom Ethernet transceiver. The radio-frequency (RF) board is manufactured with an asymmetric structure using a hybrid PTFE/FR4 substrate and is equipped with planar antennas.
The NXP Semiconductor multi-channel 77 GHz radar transceiver chipset, composed of four receivers, two transmitters and an associated voltage controlled oscillator (VCO), is used as high-frequency transmitter and receiver. The RF dies are packaged in redistributed chip package (RCP) fan-out wafer level packages initially developed and manufactured by Freescale.
Based on a complete teardown analysis of the Continental radar, the report provides the bill-of-material (BOM) and the manufacturing cost of the radar sensor.
A complete physical analysis and manufacturing cost estimation of the NXP semiconductor monolithic microwave integrated circuits (MMICs) is available in a separate report.
