PROBLEM TO BE SOLVED: To provide a noise suppression device capable of reducing the signal loss of a target and suppressing noise such as a false image.SOLUTION: A noise suppression device 100 comprises: a determination section 110 for determining whether an empty area targeting the reception signal of a target detector belongs to a target area where a target is possibly present based on a change in amplitude in the distance direction of a first signal obtained by amplifying the reception signal of the target detector; a correction value determination section 120 for performing predetermined calculation about the history of amplitude in the azimuth direction of the first signal, obtaining a calculation result in each azimuth direction, and determining which azimuth direction result is employed based on whether the result belongs to the target area, thereby determining a correction value for suppressing the noise of the reception signal of the target detector; and a noise suppression section 130 for generating an output signal to suppress the noise of the reception signal of the target detector based on the correction value. |
