Abstract: The present disclosure provides a multiple-input multiple-output (MIMO) radar system and a method for detecting an object in a scene. The method comprises transmitting frequency modulated continuous wave (FMCW) in a radio frequency (RF) band, and collecting radar measurements of the scene sampled in a time-frequency domain within an intermediate frequency (IF) bandwidth. The method further comprises transforming the radar measurements into range-doppler space to produce measurements of different segments of the scene for different range-doppler bins formed by intersections of different range bins with different Doppler bins, classifying a presence of the hypothetical transmitter at different segments of the scene according to a signal model with an internal classification, combining the results of the classification to produce parameters of the object, and outputting the parameters of the object.

Abstract: A radar system for tracking an object in a scene by transmitting frequency modulated continuous wave (FMCW) is provided. The radar system is configured to collect radar measurements of the scene sampled in a time-frequency domain within an intermediate frequency (IF) bandwidth to which reflection of the transmitted FMCW is shifted by mixing with a copy of the FMCW, where a frequency dimension of the time-frequency domain is quantized into multiple frequency bins forming the frequency bandwidth, where a time dimension of the time-frequency domain is quantized into multiple time instances forming a time interval corresponding to the PRI, count a number of amplitude peaks of the radar measurements for each frequency bin at different instances of time, identify a number of frequency bins with their counts of the number of peaks above a predetermined threshold, and determine at least a distance to the object based on frequency analysis of the radar measurements.
