Radar System Design for Static Object Detection for Indian Road Conditions

There is an increase in the adoption of radars into automobiles as it is robust to weather changes and provides direct range and velocity measurements. Several low-height static targets such as humps and potholes are difficult to detect in regular vehicles, especially when covered with water. Hence, it is necessary to study their detection based on how they interact with radar waves which are characterized by their radar cross-section (RCS). In this work, a detailed methodology for estimating the RCS of humps and potholes has been presented, and its detection is studied in two different radar waveforms, frequency-modulated continuous waveform (FMCW) and orthogonal frequency division multiplexing waveform (OFDM).
