A space scanning life body detection method based on electromagnetic waves is applied to the system, space information is obtained through a scanning unit, and the space information is calculated and analyzed through a control unit.
The method specifically comprises the following steps:
step 1: the power supply unit is started, and the control unit sends an instruction to the scanning unit;
