Claims

[Scope of utility model registration request]

In the radar signal processing device, N points (N is an integer) 'FF
T (Fast Fourier Transform
) and N amplitude detectors that detect the amplitude of their outputs, N target detectors that detect the presence or absence of a target from the output data of the N amplitude detectors, and N target detectors that detect the presence or absence of a target from the output data of the N target detectors. A Doppler characteristic detection circuit that analyzes the frequency characteristics of the target, a target data file that records the expected frequency characteristics of the target, and the output of the Doppler characteristic detection circuit and the target data file are compared to identify the target type. A radar signal processing device comprising a target identification circuit.
