Abstract
In an embodiment, a method for tracking a target includes: receiving raw data from a millimeter-wave radar, the raw data including a plurality of macro-Doppler frames, each macro-Doppler frame having N chirps, where each macro-Doppler frame stretches over a time interval having a first duration; generating micro-Doppler frames from the plurality of macro-Doppler frames, each micro-Doppler frame including L chirps from M macro-Doppler frames, where each micro-Doppler 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; and tracking a first target as the target transitions from being detected based on the macro-Doppler frames to being detected based on the micro-Doppler frames.
