Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 5:
6. A signal processing method comprising:
generating a multiple-input multiple-output (MIMO) signal including a plurality of pulse signals, and radiating the MIMO signal into space;
receiving a reflection signal resulting from reflection, by a target, of the radiated MIMO signal;
demodulating the MIMO signal from the received reflection signal;
forming beams in a plurality of different directions, by multiplying the plurality of pulse signals included in the demodulated MIMO signal by a respective plurality of different weighting coefficients;
changing noise power included in each of the formed beams in the plurality of directions, by shifting a phase of the generated MIMO signal and adjusting the plurality of weighting coefficients on a basis of an amount of phase shift of the phase; and
detecting the target from each of the formed beams in the plurality of directions.
