The invention relates to the field of radar electronic technology in automobile application, in particular to a design method for a heavy truck accurate reversing auxiliary parking radar system. The method comprises the following specific steps of: S1, modifying radar performance indexes according to an application scene to realize short-distance high-precision multi-resolution performance; S2, installing the radar at the corresponding position behind the vehicle, and obtaining obstacle state information; S3, transmitting the obstacle state information to a radar processing unit for subsequentprocessing; and S4, notifying a driver of a result obtained after the target danger level is judged through the processing unit, and realizing horizontal observation and obstacle resolution and pitching resolution of vertical obstacles in the aspect of obstacle detection through the 77-GHz millimeter-wave radar to form a three-dimensional (3D) obstacle model which is not influenced by weather andenvironment factors. And the processing system prompts a driver of the target information to perform corresponding vehicle operation, so that the accuracy is high.
