Abstract
A process for detecting and discriminating a particular target, such as an ambulating human, amidst an environment crowded with other objects or humans having similar doppler profiles to the desired target. A method according to one embodiment includes generating an initial radar image corresponding to a received doppler profile of a target, and generating a matched filter signal corresponding to the received doppler profile. The matched filter signal is correlated with subsequently received radar images to detect and discriminate the target.
Claims8
A method comprising:
- generating an initial radar image corresponding to a received doppler profile of a target;
- generating a matched filter signal corresponding to the received doppler profile of the target;
- generating a subsequent radar image;
- and
- correlating the matched filter signal with the subsequent radar image to discriminate the target.
