Millimeter-wave radar system based on water supply system application and using method thereof

The invention discloses a millimeter-wave radar system based on a water supply system application and an application method thereof, and relates to the field of radar control. The system comprises a millimeter wave microstrip transmit-receive antenna, a radio frequency unit, a processing unit, a control interface and a water supply solenoid valve. The method comprises the following steps: S1, using a millimeter wave transmit-receive microstrip antenna to transmit an electromagnetic wave signal and receive a target echo signal, and sending the echo signal to a radio frequency unit; S2, performing frequency conversion on the echo signal in the radio frequency unit to obtain an intermediate frequency echo signal, and sending the intermediate frequency echo signal to a processing unit; S3, using the processing unit to perform sampling and signal processing on the intermediate frequency echo signal, judgeing whether a dynamic target exists or not, and outputting an turn-on signal if the dynamic target exists; exec
