The invention relates to the technical field of intelligent driving, and provides a distributed single radar radio frequency circuit, a chip system and a vehicle sensing system, and the vehicle sensing system comprises a vehicle-mounted domain controller and a plurality of radars deployed in a distributed manner. The circuit comprises a radio frequency unit and a serial coding unit, wherein the radio frequency unit comprises a transceiver and a sampling module. The radio frequency unit is used for transmitting millimeter waves to at least one object in the driving environment of the vehicle after receiving the wave transmitting instruction; the transceiver is used for receiving millimeter waves reflected by at least one object; the sampling module is used for carrying out ADC sampling on millimeter waves reflected by at least one object to obtain initial sampling data and sending the initial sampling data to the serial coding unit; the serial coding unit is used for coding the initial sampling data to obtain target sampling data and transmitting the target sampling data to the vehicle-mounted domain controller; and the vehicle-mounted domain controller is used for analyzing the vehicle-mounted domain controller to obtain vehicle sensing data for deciding a driving instruction of the vehicle. According to the scheme, low-power-consumption and low-cost target calculation work can be realized, and the implementation difficulty is low.
