ABSTRACT:
A DSSS (Direct Sequence Spectrum Spreading) radar has a transmitting part to transmit a transmitting signal, including a predetermined code sequence, to one or a plurality of targets, a receiving part to receive a received signal corresponding to the transmitting signal which has been reflected from the one or a plurality of targets, and a computing part. The computing part computes a sum signal and a difference signal of received signals received by the receiving part at different points in time, and obtains a Doppler frequency of the one or a plurality of targets based on a phase difference between the sum signal and the difference signal.
