Patent ID: 7355925

Claim:
A method of processing signals received corresponding to an emitted signal, the emitted signal comprising by recurrence two pulses, a first Doppler tolerant broadband pulse and a second Doppler intolerant broadband pulse, said method comprising: detecting objects performed on the part of the signal received corresponding to the first Doppler tolerant broadband pulse transmitted at each recurrence and providing an alarm for each object detected; applying a matched filtering to the signal received corresponding to the second Doppler intolerant broadband pulse transmitted for each recurrence, said filtering making, for each detected object having satisfied at least a predetermined criterion of selection, correlations between said signal and several dopplerized copies of said transmitted second pulse, said correlations producing several signals corresponding to several Doppler channels; and performing a Doppler classification of the detected objects; wherein said Doppler classification is performed by comparing with a threshold the Doppler of every detected object having satisfied at least a predetermined criterion of selection, this Doppler being determined from the signals resulting from the application of the matched filtering.
