RADAR-BASED TARGET TRACKER

A method for tracking a target is provided. The method comprises:receiving raw data from a millimeter-wave radar, the raw data comprising a plurality of macro-Doppler frames, each macro frame having N chirps, N being a positive integer greater than 1, wherein each macro frame stretches over a time i...

Zusammenfassung:	A method for tracking a target is provided. The method comprises:receiving raw data from a millimeter-wave radar, the raw data comprising a plurality of macro-Doppler frames, each macro frame having N chirps, N being a positive integer greater than 1, wherein each macro frame stretches over a time interval having a first duration;generating micro-Doppler frames from the plurality of macro-Doppler frames, each micro frame comprising L chirps from M macro-Doppler frames, M being a positive integer greater than 1, L being a positive integer greater than 1, wherein each micro frame stretches over a time interval having a second duration that is longer than the first duration;detecting one or more moving targets based on the macro-Doppler frames;detecting one or more static targets based on the micro-Doppler frames; andtracking the target as the target transitions from being detected based on the macro-Doppler frames to being detected based on the micro-Doppler frames.
