The authors consider the possibility of defining the trespasser’s size and rate of motion in the protected zone of a radar technical protection system by restoring the transmission function according to the trespasser’s diffraction pattern. The authors have obtained algorithms of defining the trespasser’s size in the additive signal-noise mixture, as well as their variants for the case of defining the trespasser’s size according to the displaced realizations of the receiver’s output signal.
