Accurate Target Localization for Automotive Radar

Abstract

Automotive radars suffer from low angular estimation accuracy due to the limited number of antennas and insufficient onboard processing power. This paper addresses the single target tracking problem in automotive radar by using recently proposed MIMO-monopulse approach which blends the monopulse approach with the collocated MIMO radar. We demonstrate and compare the localization performance of the MIMO-monopulse at an automotive radar on a real-world scenario. Experiments show that MIMO-monopulse results in a better angular accuracy comparing to the conventional digital beamforming even though the low-level processing power.
