PURPOSE:To accurately identify a target by identifying the Doppler spectrum of fluctuations of the target body and the Doppler spectrum of fluctuations of a target body model simulated from features showing the structure of the target body model. CONSTITUTION:A target fluctuation detecting machine 8 detects a Doppler frequency which is a feature of the fluctuations of the target from a Doppler spectrum generated by the fluctuations of the target body and a wave feature input device 9 inputs the features of ocean waves to a target feature detector 10. The target feature detector 10 detects the features showing the structure of the target from the input Doppler frequency and the features of the ocean waves. The features showing the target body model and its structure are registered previously in a target feature data base controller 11. Then a target fluctuation simulator 12 simulates the Doppler spectrum of fluctuations of the model from the features showing the structure of the target body the features showing the structure of the target body model, and the period and amplitude of the ocean waves and a target identifier 13 identifies the target by correction processing between the Doppler spectrum of fluctuations of the target body and the simulated Doppler spectrum of fluctuations of the model.
