Fundamental Study on Ambiguity Suppression of Automotive Squint-Mode MW-SAR by Using SIMO Radar

Automatic operating system for vehicle has been widely studied. Especially, Millimeter wave (mmWave) automotive radar has been attracting attentions. Synthetic Aperture Radar (SAR) by using mmWave radar can obtain high-resolution 2-D images. Depending on the speed of the vehicle and the performance of the radar, grating lobes are generated in observing area. Using Single Output Multiple Output (SIMO) radar is a method of solving this problem. In this paper, we provide some computer simulation results and show ambiguity suppression of grating lobes by using SIMO radar.
