Problems solved by technology
[0002] Traditional shore-based radar clutter suppression processing methods are mainly for single-frame target image data processing, and do not use the orderliness of target multi-frame data and the disorder of clutter multi-frame data in the same grid unit to deal with clutter. wave to extract target
In addition, the inter-frame correlation processing is generally based on the sampling points between frames and the processing is not based on the grid unit. This sampling point processing method is not processed by the smallest unit, which may easily lead to the loss of weak targets.

Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0040] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0041] In addition, in describing the present invention, the terms used are for the purpose ...

The embodiment of the present invention discloses a shore-based radar clutter suppression processing method, including: S1, in the current frame radar echo image, determine whether the azimuth unit of the current scan line and the previous scan line are the same azimuth unit, if yes Then enter S2, otherwise update the data of the previous azimuth unit and then enter S2; S2, determine whether the distance unit at the corresponding position of the echo on the current scanning line in the previous frame of the radar echo image is marked as an echo , if yes, display the echo on the current scan line, otherwise delete; S3, record the azimuth of the current scan line and enter the next scan line, repeat S1~S2 to the last scan line; S4, for continuous multi-frame radar Echo image, repeat S1~S3. The embodiment of the invention also discloses a shore-based radar clutter suppression processing system. The invention can effectively suppress disordered clutter and extract ordered targets, and weak and small targets will not be lost after multi-frame correlation processing.

technical field [0001] The present invention relates to the field of radar technology, in particular to a shore-based radar clutter suppression processing method and system. Background technique [0002] Traditional shore-based radar clutter suppression processing methods are mainly for single-frame target image data processing, and do not use the orderliness of target multi-frame data and the disorder of clutter multi-frame data in the same grid unit to deal with clutter. wave to extract the target. In addition, inter-frame correlation processing is generally based on sampling points between frames and not based on grid units. This sampling point processing method is not processed by the smallest unit, which may easily lead to the loss of weak targets. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a shore-based radar clutter suppression processing method and system, which can effectively suppres...
