description The invention discloses a non-line-of-sight moving target sensing system and method based on WiFi signals in the field of non-line-of-sight moving target sensing, and the system comprises a signal receiving and transmitting unit and a data analysis unit, and the signal receiving and transmitting unit is composed of a signal transmitting module and a signal receiving module. Compared with a traditional moving target sensing device based on WiFi, under the condition that equipment does not need to be arranged in advance, a single machine achieves the sensing function, WiFi signals are received and transmitted through a system, the flash effect of fixed objects such as a wall is eliminated through a static zero clearing algorithm, and then through collecting and analyzing the channel state change of the received signals based on static zero clearing, the moving target sensing device based on WiFi is obtained. According to the method, data are substituted into an inverse synthetic aperture radar model to calculat
