Abstract

Abstract:

In recent years, automotive millimeter-wave radars have been widely launched in vehicles as a popular sensing solution in driving assistance areas. Based on the urgent need of the RSE test of similar products, this paper demonstrates how automotive millimeter-wave radar works, illustrates the standards in different areas and puts forward a laboratory RSE test method for 77-79 GHz automotive millimeter-wave radar products, a solution which can highly improve the testing efficiency and evaluate the performance accurately.

Key words: automotive millimeter-wave radar, current situation, RSE tests
