摘要
A SAR apparatus including: a radar transceiver to emit electromagnetic pulses and to provide a radar signal in response to echoes of the electromagnetic pulses; and a processing unit, configured to produce SAR images of moving objects from the radar signal. The processing unit includes: a first processing module to apply translational motion compensation to a central reference point of a moving object in a subaperture of the radar signal; a second processing module, to execute phase compensation with the single central reference point as reference; and a third processing module to apply phase compensation to the radar signal as a function of an estimated phase component the auxiliary point and of a normalization parameter to a distance in range between the central reference point and the auxiliary point.
