PURPOSE: A target search calculation structure of a RADAR(RAdio Detection And Ranging) signal processing apparatus is provided to search efficiently a target by changing a calculation structure of the radar signal processing apparatus. CONSTITUTION: The first data set(110) outputs data(D11,D12,D13) according to pulses of the first channel. The first CFAR(Constant False Alarm Rate) portion(120) includes the first, the second, and the third CFAR devices(121,122,123) in order to receive the data(D11,D12,D13) of the first data set(110) and perform CFAR operations. The second data set(130) outputs data(D21,D22,D23) according to pulses of the second channel. The second CFAR portion(140) includes the fourth, the fifth, and the sixth CFAR devices(141,142,143) in order to receive the data(D21,D22,D23) of the first data set(110) and perform the CFAR operations. An OR gate portion(150) includes the first, the second, and the third OG gates(151,152,153) in order to calculate output signals of the first to the sixth CFAR devices(121,122,123,141,142,143). A 2/3 integrator(160) is used for obtaining a final target by integrating targets of each OR gate(151,152,153) of the OR gate portion(150).
