Abstract： When mmwave radar makes the manned or unmanned detection in the smart home environment, leather sofa reflects a strong signal because of its material itself, the strong reflection signals would bring a great disturbance, and finally cause false alarm. Aiming at this problem, a specific parameters through the human body breathe the margin of ups and downs in the chest wall was obtained , and the threshold was setted, coupled with the breathing frequency of the low frequency limit, and by choosing specific 4 root virtual antenna can achieve the threshold number do some judgement, greatly eliminating the false alarm interference of leather sofa.
Key words : mmwave radar; manned and unmanned detection; false alarm
