Low Cost 76GHz Radar Target Simulator and Test System

In this paper we discuss the test requirements for 76GHz automotive radar. We give an overview of automotive radar systems and then present a low-cost Radar Test System (RTS) which addresses the measurement requirements of the radar in R&D and production environments. The low-cost system is based on the original Anritsu RTS but utilizes L.O. tracking schemes to minimize the instantaneous bandwidth required of the delay devices and utilizes a novel technique for generating false Doppler. The RTS provides a moving target simulator for testing the radar sensor, and it provides mm-wave signal analysis for power and spectral characterization of the radar transmitter.
