Abstract
A method includes receiving a signal, which includes reflections of multiple pulses from one or more targets (24). A Doppler focusing function, in which the reflections of the multiple pulses from each target accumulate in-phase to produce a respective peak associated with a respective delay and a respective Doppler frequency of the target, is evaluated based on the received signal. Respective delays and Doppler frequencies of the targets are estimated based on the Doppler focusing function.
