Abstract
A signal processing device performs object detection processing in which peak signals each representing a differential frequency between a transmitted signal in which a frequency thereof changes in a predetermined cycle and a received signal are derived in a first period where the frequency of the transmitted signal rises and a second period where the frequency of the transmitted signal falls, and the peak signals in the first period are paired with the peak signals in the second period to detect object information related to the peak signals. A range setting unit sets a frequency range in each of the first period and the second period on the basis of a frequency of an integer multiple of the peak signal related to the object information which has been detected in previous object detection processing. A signal setting unit sets a peak signal as a specific peak signal in a case where the peak signal is within the frequency range in each of the first period and the second period. A paring unit pairs the specific peak signal in the first period and the specific peak signal in the second period.
