In an embodiment, a method includes: initializing a crosstalk compensation factor indicative of a transmitter-receiver crosstalk between a transmit path of a radar sensor and a receive path of the radar sensor; receiving radar data from the radar sensor; selecting a set of data from the radar data; performing target detection on the set of data; and after performing the target detection on the set of data, when no target is detected in the set of data, updating the crosstalk compensation factor based on the set of data and, after updating the crosstalk compensation factor, generating a radar spectrum based on the radar data and the crosstalk compensation factor, and when a target is detected in the set of data, generating the radar spectrum based on the radar data and the crosstalk compensation factor without updating the crosstalk compensation factor.

Adaptive Tx-Rx crosstalk cancellation for radar systems

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.
