High performance automotive radar signal processing on TI's TDA3X platform

Abstract

Automotive is an important application of radar. In collision avoidance applications, radar and camera are two main sensors with radar having a healthy share [16]. Usage of radar in the automotive space is expanding beyond range and velocity detection of obstacles to more sophisticated usage of object motion direction estimation [17], precise angular position estimation of obstacles in urban environments [6][7] and ground vehicle localization[15]. As a result, radar processing solutions require complex signal processing with higher programmability. In this paper, we explain the mapping of automotive MIMO radar processing chain on TI's TDA3x platform and highlight the need for a heterogeneous processor architecture with adequate programmability.
