Method for detecting at least one target by pulse-Doppler radar with unambiguous measurement of radial velocity and pulse-Doppler radar for implementing such a method

摘要

method of detecting at least one target by pulse doppler radar having the following steps:(a) to generate a series of pulses of coherent radio frequency separated from a temporal interval (r (k)) varied from one pulse to the next.(b) receive signals that contain (e) of the pulse echoes from the target or at least one, demodulate and sample.(c) the filter through a plurality of filters (f - n. fo...in each said filter is a filter suitable for the burst of pulses with a frequency offset at least some of the different filters belong to the same class of ambiguity, corresponding to frequency shifts between multiple are spaced a fr u00e9quence average pulse repetition of the series; and(d) resolving the ambiguity in determining the frequency of the output signals of the filter in the same class of ambiguity, the higher level.;pulse doppler radar for the implementation of such a process.
