Embodiment Construction
[0094] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0095] The ground clutter processing method provided by this application can be applied to such as figure 1 shown in the application environment. Such as figure 1 As shown, the server 101 and the radar 102 communicate through a network (wired and / or wireless network), wherein the server 101 can be an independent server, or a server cluster composed of multiple servers. In other optional embodiments, The server 101 can also be set in the car, or be integrated with the radar 102 as an integral device. The radar 102 can be a millimeter-wave radar, or other types of radars....

The invention relates to a ground clutter processing method and device, computer equipment and a storage medium. The method comprises the following steps that a server obtains data of a plurality of original target points, screens out candidate ground clutter points from the plurality of original target points based on a pitch angle in the data, and screens out target ground clutter points from the candidate ground clutter points based on a distance and a signal-to-noise ratio in the data. In the method, a server performs preliminary ground clutter point screening on an original target point according to a pitch angle of a target object acquired by a radar, determines candidate ground clutter points, and further screens the candidate ground clutter points according to a distance and a signal-to-noise ratio; combined is carried out screening on multiple dimensions such as the pitch angle, the distance, the signal-to-noise ratio and / or the speed, so that problem that a short-distance weak target is cut at a time is avoided, the target ground clutter points are screened through the method, and the recognition precision of the ground clutter points is relatively accurate.
Description
technical field [0001] The present application relates to the technical field of target detection, in particular to a ground clutter processing method, device, computer equipment and storage medium. Background technique [0002] When the sensor is used for target detection, it is often affected by clutter from other directions, which will lead to inaccurate target detection results. Among them, the most important and most influential clutter is the ground clutter reflected from the ground. Ground clutter can not only cause false targets, but also affect the detection of weak and small targets at close range. Therefore, the processing method of ground clutter is important in target detection. plays an important role in the process. [0003] The current ground clutter processing methods generally deal with ground clutter by raising the short-distance detection threshold, that is, the original detection points whose signal-to-noise ratio is lower than the ground clutter detect...
