method of preparation of a radar echo signal, produced by a target, to compensate for the effects of degradation of the signal due to the motion of the target.

摘要

Herein described is a processing method (100) of a radar echo signal, which is generated by a target, in order to compensate for degradation effects introduced in said signal by target motion, the method (100) comprising the following steps: - determining (102-106) the value of at least one target motion parameter by selecting from a plurality of possible test values ( VR 1 ,...,VR N ) one value (VR) which maximizes a functional defined over the radar echo signal; - performing a correction (107) of the radar echo signal based on said value (VR) which is determined by the at least one motion parameter. Said functional is the time derivative of the radar echo signal or a function dependent from said derivative.
