1. An object detector comprising:
at least one processor configured to implement:
a transmission and reception unit that transmits a transmission wave and receives a reflection wave from a plurality objects;
an acquisition unit that detects the reflection wave having a signal level including a plurality of peaks above a threshold to acquire a plurality of pieces of distance information each indicating a distance from the transmission and reception unit to each of the plurality of objects corresponding to each peak;
a sort processing unit that sets a priority of the distance information to be higher as a difference between each of the peaks in the signal level corresponding to the distance information and the threshold is larger when the plurality of pieces of the distance information are acquired in a predetermined period; and
an output control unit that outputs the plurality of pieces of the distance information in descending order of the priority.
