The invention provides an indoor moving object detection method based on Wi-Fi wireless perception. The indoor moving object detection method comprises the following steps: a Wi-Fi transmitter and a receiver are arranged in the detection area, wherein the transmitter continuously transmits Wi-Fi signals, and the receiver continuously receives the Wi-Fi signals at the set frequency and analyzes theCSI data from the received Wi-Fi signals; and the amplitude information of the CSI data is calculated, the CSI amplitude fluctuation of each receiving antenna of the receiver is analyzed, whether theCSI amplitude of each receiving antenna has phase difference is judged, the judgment result indicates existence of the moving object in the detection area if the phase difference exists, or the judgment result indicates no existence of the moving object in the detection area. According to the method, the random noise interference randomly distributed on each receiving antenna and generated by thesurrounding electromagnetic environment or other equipment interference, the interference of the cross-correlation noise having cross-correlation on each receiving antenna caused by the voltage levelchange of the equipment and the interference of the indoor multipath effect can be effectively solved.
