Multibeam radar system used in vehicle for object detection, includes switches to selectively connect receiving antenna and evaluation device to mixer

摘要

A directional coupler (2) branches the radar beam signals from a voltage controlled oscillator (VCO) (1) to a mixer (3) and transmission antennas (6a). The switches (5a,5b) selectively connect the receiving antennas (6b) and evaluation device (8) to the input and output of the mixer, respectively.
