Abstract
A novel and useful two-stage radar return data processing mechanism for use in FMCW radar systems that divides the conventional frame into two portions. Two different frames are transmitted rather than one. The frames are transmitted consecutively one after the other. A low resolution 'coarse' frame is first transmitted that is fully processed in real time. Based on the results of the processing of the coarse frame, a plurality of targets of interest (TOIs) in the scene representing a subset of the received data is determined. Then a longer high-resolution 'fine' frame is transmitted and processed using the information obtained in the previous coarse fame. Using the TOI information obtained in the previous coarse frame, only a subset of the received data is processed. The non-processed portion is assumed to contain non-interesting information and is discarded or ignored thereby significantly reducing processing time.
