1. A range side lobe removal device, comprising:
- a pulse compressor for acquiring a reception signal from a radar antenna and generating a pulse-compressed signal by performing a pulse compression of the reception signal;
a pseudorange side lobe generator for generating a pseudo signal of range side lobes of the pulse-compressed signal based on the reception signal; and
a signal remover for removing a component corresponding to the pseudo signal from the pulse-compressed signal.
