DEVICE AND METHOD FOR DETECTING WAVE SOURCE

摘要

PROBLEM TO BE SOLVED: To restrain intensity of a false image estimated in detection of a wave source. SOLUTION: Reception signals of a wide band coming from the wave source reflecting one or more of pulses of which the transmission frequency ranges over a wide band are accumulated in a memory 41. A super-resolution processor 43 detects the wave source based on a delay time providing a peak of an amplitude value of an evaluation function with respect to the minimum eigenvalue of an average correlation matrix calculated based on the reception signal, and intensity of the wave source based on an estimated value of the lag time, and a false image suppressor 44 conducts weighing to the intensity of the wave source detected by the processor 43 to restrain the false image detected erroneously as the wave source.
