Contents I. Introduction
During past few years, autonomous vehicles or self-driving cars have witnessed enormous development in vehicular control [1], environmental sensing [2], in-vehicle entertainment [3], efficient resource utilization [4], and intervehicular synchronization [5]. An ongoing challenge is target detection and recognition in order to avoid road accidents and boost automotive safety. Conventional target detection techniques use sensors, such as lidar, camera, and infrared/thermal detectors. However, only radar offers the advantage of robust detection in adverse vision and weather conditions [2]. Currently, millimeter-wave (mm-Wave) (77 GHz) automotive radars are the preferred radar technology for target detection because they have wide bandwidths (∼4–7 GHz) and, hence, high range resolution [6]–[8].
