Complex environment vehicle-mounted millimeter wave radar weak target detection method and system

Abstract

The embodiment of the invention relates to the technical field of vehicle-mounted millimeter wave radars, and particularly discloses a complex environment vehicle-mounted millimeter wave radar weak target detection method and system. According to the embodiment of the invention, echo detection data are obtained through a vehicle-mounted millimeter wave radar; carrying out clutter analysis and suppression processing; determining a weak target, and performing feature extraction and feature enhancement; carrying out target correlation analysis and trajectory; and predicting a stage action track of the weak target, and carrying out evaluation and early warning processing on a driving risk. Echo detection data can be obtained, preprocessing, clutter analysis, braking processing and target analysis are carried out, a weak target is determined, feature extraction, feature enhancement processing, target correlation analysis and trajectory processing are carried out on the weak target, then stage action trajectory prediction is carried out, vehicle driving data are obtained, and driving risk assessment and early warning processing are carried out. When the vehicle-mounted millimeter wave radar is applied to a complex environment, efficient and accurate detection and motion prediction can be carried out on a weak target, and the driving safety is improved.
