The invention provides a radar echo data processing method and device, a storage medium and terminal equipment, a first preset number of reference points are screened out from all target points, the signal-to-noise ratio of any reference point is greater than the signal-to-noise ratio of a non-reference point, and the signal-to-noise ratio of any reference point is greater than the signal-to-noise ratio of the non-reference point. The target point is a point higher than a one-dimensional distance threshold in a one-dimensional distance spectrum corresponding to the radar echo data; all non-reference points are classified according to the reference points, a target category is determined, and the number of target points in the target category is larger than or equal to a second preset number; and outputting the target parameter information of the target point in the target category. And only the target parameter information of the target points in the target category is reserved and output, interference data in the target points are screened out, and the accuracy of the output target parameter information is further guaranteed.
Description
technical field [0001] The present application relates to the field of radar, in particular, to a radar echo data processing method, device, storage medium and terminal equipment. Background technique [0002] Millimeter-wave imaging radar is widely used in various industries, such as the automotive field and the drone field. Different from the two-dimensional high-resolution requirements of millimeter-wave imaging radar in the automotive field, the imaging radar in the UAV field is mainly used to realize the autonomous obstacle avoidance of UAVs. For drones working in the agricultural field, radar needs to accurately detect objects that need to avoid obstacles such as trees, aerial wires, and utility poles in the scene, as well as objects that are easily observed such as the ground, canals, and dams. [0003] Because the drone needs to bypass the monitored target during its operation, if a false detection occurs, it may affect the operation of the drone and even pose a saf...
