Abstract

The present disclosure provides a radar apparatus capable of suppressing a radar-to-radar in-band interference caused by a signal derived from another radar apparatus in a radar system in which a plurality of radar apparatuses share frequency resource to increase a frequency utilization efficiency. The radar apparatus includes: a receiver configured to acquire a received signal; a plurality of matched filters arranged in parallel to filter the receive signal, each corresponding to respective one of the plurality of radar apparatus to use a transmit signal of a corresponding radar apparatus as a reference signal; and a signal reconstructor configured to select a matched filter most adequate for an interference suppression based on outputs of the plurality of matched filters, subtract the reference signal of a selected matched filter at least partially from the receive signal, and reconstruct a desired echo signal to be used to determine a target.
