Automobile anti-collision radar system

The invention discloses an automobile anti-collision radar system. The system comprises a monolithic microwave integrated circuit, a field-programmable gate array (FPGA) and a display unit, wherein the monolithic microwave integrated circuit is connected with a transmitting antenna and a receiving antenna of a radar on an automobile and is used for controlling the transmitting antenna to emit a radio-frequency signal and controlling the receiving antenna to receive an echo signal, and obtaining an intermediate frequency signal based on the radio-frequency signal and the echo signal, the intermediate frequency signal being a difference frequency signal between the radio-frequency signal and the echo signal; the field-programmable gate array is connected with the monolithic microwave integrated circuit, and is used for receiving the intermediate frequency signal sent by the monolithic microwave integrated circuit and carrying out processing on the intermediate frequency signal to obtaindetection information, an
