[0003] However, the radar shielding area provided in the prior art is a regular figure such as a rectangle, a sector, or a ring. When facing terrain such as coastlines and islands, the shape is too rough to outline the outline of the actual area, resulting in the accuracy of target detection. low, easy to cause misjudgment

Embodiment Construction
[0064] In order to make the objects, technical solutions and advantages of the present application, the present application will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.
[0065] Since the shore of the Sea Surface Targets are typically used to detect target objects on the sea, not on land, islands and other areas, therefore, the applicable shore of the Sea Surface Targets are typically used to detect environmental and board testing streets, indoor environment, such as ground radar very different, further, the vehicle-mounted radar and other types of radar target detection method is not applicable for the shore of the Sea Surface targets. For simplicity of description, hereinafter referred to as ground based radar Sea Surface Targets for subsequent omitted.

The invention relates to a radar-based target detection method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a given area drawn by a user, and determining a target boundary formed by taking a radar center as a circle center and a preset distance as a radius; determining a current orientation in a plurality of orientations uniformly arranged in a scanning range of the radar, and determining a line segment taking the center of the radar as an end point on the current orientation; determining a plurality of intersection points and a plurality of sub-line segments of the line segment and the given area; determining a flag bit corresponding to each line segment; traversing all orientations in the scanning range of the radar, and obtaining a plurality of flag bits on each orientation; when the detection echo signal of the target object is received, obtaining a plurality of scanning sampling points of the target object; and obtaining a detection result of whether the target object is in the given area according to the flag bits corresponding to the sub-line segments where the plurality of scanning sampling points are located. By adopting the method, the detection accuracy can be improved.
Description
Technical field [0001] The present application relates to the field of radar technologies, in particular to a target detection method, apparatus, computer device, and storage medium based on radar. Background technique [0002] Since the shore base is mainly monitored at sea, it does not require monitoring of land and islands, etc. Discover and track the effect. On the other hand, due to the vast sea area, it is sometimes necessary to focus on maritime traffic or other hotspots. Thereby, the shield area is needed to make the radar no longer monitor and track the target in the shielding area. [0003] However, the radar shielding area provided in the prior art is a rectangular, sector or ring, etc., facing the coastline, the shape of the island is too rough, and the protrusions of the actual area cannot be outlined, resulting in accuracy when the target is detected. Low, it is easy to cause miscrosis. Inventive content [0004] Based on this, it is necessary to provide a radar-ba...
