13. A signal processor, comprising:
a signal processing unit configured to perform signal processing on a beat signal generated from an echo signal obtained from a reflection of a transmission signal that is sequentially transmitted from each transmitting antenna in a plurality of transmitting antennas at times that are anterior-posterior symmetrical centered around a reference time from a target and a local signal, the transmission signal being based on the local signal, wherein the signal processing unit synthesizes a synthesized beat signal at the reference time from a first beat signal received by the receiving antenna before the reference time and a second beat signal received after the reference time.
