Embodiment Construction

[0042] Below in conjunction with accompanying drawing this patent is further explained and illustrated. But the scope of protection of this patent is not limited to the specific implementation.

[0043] like figure 1 , 2 As shown, an adaptive extraction method of target / interference area in a warning radar PPI image. For an image with only targets and no interference, the visual saliency method is used for adaptive extraction of the target area. For the case of interference, the color transformation based The self-adaptive extraction method of this paper attempts to automatically extract the target and interference area in the warning radar PPI image, and at the same time suppress the background information in the PPI image, so as to provide data support for the classification of interference; the steps are as follows:

[0044] 1) Adaptive extraction of target area based on visual saliency method

[0045] Visual salience is mainly characterized by the application of pixel b...

Abstract

The invention belongs to the technical field of interference detection and effect evaluation, and discloses a warning radar PPI image target/interference region self-adaptive extraction method, whichis used for performing target region self-adaptive extraction on an image only with a target without interference by applying a visual saliency method. For a target region in case of interference, theself-adaptive extraction method based on color transformation is adopted to attempt to realize the automatic extraction of a target and an interference area in a warning radar PPI image. Meanwhile, the suppressing background information in the PPI image at the same time, thereby providing data support for interference classification. According to the invention, the automation degree of PPI imageanalysis of the alert radar can be improved, on one hand, the processing efficiency can be improved, and on the other hand, the analysis deviation caused by human factors can be reduced. The method has the advantages of firstly, a target area self-adaptive extraction step based on a visual saliency method; and secondly, a target and interference region self-adaptive extraction step based on colortransformation.

Description

technical field [0001] The invention belongs to the technical field of interference detection and effect evaluation, in particular to a method for adaptively extracting a warning radar PPI image target / interference area. Background technique [0002] Warning radars are usually deployed at the frontiers of frontier defense / coastal defense or important military locations, and perform tasks such as searching and tracking air targets and sea targets in a certain area around the deployment site, so as to realize early warning and detection of threatening targets. Usually the search results of the warning radar will be presented on the Plan Position Indicator, PPI. On the PPI, the radar antenna is located in the center of the display area, and the radar echo processing results are displayed in polar coordinates, indicating the distribution of various echoes: target, interference, clutter, etc. in distance and azimuth. The map of the terrain where the radar is located is embedded ...
