Patent attributes
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 (R11 to R1M), . . . , (RN1 to 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 ϕ1 to ϕM set as different arrays of known discrete values and that generates a plural number P of demodulated signals (R′11 to (R′1M), . . . (R′N1 to R′NM), and includes a phase adjuster that adjusts difference among the phases of a plural number P of demodulated signals (R′11 to R′1M), . . . , (R′11 to R′NM) according to the arrays of known discrete values and generates a plural number P of in-phase signals (r11 to r1M), . . . , (rN1 to rNM).
