とを特徴とするレーダ信号処理装置。 A CFAR circuit that generates a threshold for target detection, a comparison circuit that compares the threshold with the input that performs detection, a serial/parallel conversion circuit that converts the output into parallel data, and control according to the field situation. A control circuit that outputs a signal, and a ROM (Read Only Memory) that uses the output of the serial/parallel conversion circuit and the output of the control circuit as input data to detect the start of data and the end of continuous data.
a counter that counts the signal of the start of data detected in the ROM to a certain value as a trigger; a flip-flop to which the output of the counter and the signal of the start of data detected in the ROM are input; and an output of the flip-flop. A radar signal processing device comprising an AND circuit that performs an AND operation on a signal at the end of a ROM.
