Abstract
Radar transmitter includes a plurality of transmit antennas that transmit a plurality of transmission signals using a multiplexing transmission, and a transmission circuit. The transmission circuit applies phase rotation amounts corresponding to combinations of Doppler shift amounts and code sequences to the plurality of transmission signals. Each of the combinations of the Doppler shift amounts and the code sequences has at least one different from other combination. The number of multiplexes of the code sequence corresponding to at least one of the Doppler shift amounts in the combinations is different from the number of multiplexing of code sequences corresponding to the remaining Doppler shift amounts.
