Abstract

A method for human detection includes: receiving first and second echo signals using a millimeter-wave radar to produce first and second sets of data, respectively; selecting first and second angles based on the first and second sets of data, respectively; performing a FrFT on the first set of data using the first angle; identifying first targets by comparing peaks of the FrFT of the first set of data with a first threshold; performing a FrFT on the second set of data using the second angle; identifying second targets by comparing peaks of the FrFT of the second set of data with the first threshold; generating a set of target tracks based on the identified first and second targets; and associating a target track with a human track based on comparing each target track of the set of target tracks with a set of reference track signatures.
