Signal processing and waveform generation in the side zone automotive radar

Abstract

Recently, a "Side Zone" automotive radar, also known as the Side Detection System (SDS), has been introduced. The radar has a significant amount of signal processing aimed at tracking targets, estimating ground speed, and rejecting clutter. Introductory papers give an overview of the radar including performance requirements, requirements analysis, architecture design, signal processing, block diagrams, and test result summaries. This paper is primarily concerned with, and expands on, the signal processing techniques used in the SDS radar. Also, the method of waveform generation is described in detail, as it is intricately related to the radar signal processing.
