Abstract

An orthogonal separation device of the invention includes a demodulator that performs a demodulation process corresponding to each of a plural number N of antennas for each of a plural number P (=M×N) of pulse waves (Rto RM), . . . , (RNto RNM) which arrives at the plural number N of antennas by transmitting, at the same time, a plural number M of pulse waves having phases ϕto ϕset as different arrays of known discrete values and that generates a plural number P of demodulated signals (R'to (R′), . . . (R′to R′), and includes a phase adjuster that adjusts difference among the phases of a plural number P of demodulated signals (R′to R′), . . . , (R′to R′) according to the arrays of known discrete values and generates a plural number P of in-phase signals (rto rM), . . . , (rNto rNM).
