Abstract
A range-direction frequency domain converting unit (-) converts reception video signals into signals in a range direction frequency. A hit-direction frequency domain converting unit (-) converts the signals in the range direction frequency into signals based on the velocity and the range direction frequency so that the target Doppler frequency belongs to the same velocity bin number independently of variations in frequencies of transmission signals. A correlation unit (-) generates signals based on the velocity separated for each of the transmission frequencies and a range after correlation. An integration unit (-) generates band-synthesized signals based on the velocity and a range after correlation. A candidate target detecting unit () detects candidate targets based on the signal intensity from the output signals of the integration unit (-). A target relative velocity/relative range/arrival angle calculating unit () calculates the relative velocity, the relative range, and the arrival angle of the candidate targets.
