Problems solved by technology

However, because the SAR image is larger than the natural scene image and the scene is more complex, the airport detection method based on visual attention has a large amount of calculation, and is susceptible to interference from urban areas and other areas, resulting in missed detection or false alarms.

Abstract

The invention belongs to the radar remote sensing application technology field and particularly relates to a synthetic aperture radar (SAR) airport detection method based on linear segment aggregation. According to the method, a line segment detector (LSD) is improved and is made to be suitable for SAR image line segment detection; on this basis, breadth-first search is carried out to aggregate line segments to acquire an airport support area; proposed selective non-negative maximum-value suppression is utilized to acquire a potential airport area from the airport support area; and lastly, false alarm control and significance analysis are utilized to acquire the final airport area. The method is advantaged in that better detection performance is acquired through line segment aggregation and significance analysis, and detection efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of radar remote sensing applications, and in particular relates to a synthetic aperture radar airport detection method based on line primitive aggregation. Background technique [0002] Synthetic Aperture Radar (SAR) has the characteristics of all-time and all-weather, and is an important means of earth observation. SAR target detection is the use of SAR images to locate the target position. It has clear application requirements in military fields such as battlefield reconnaissance and precision strikes. It is one of the key technologies to improve the information perception ability of SAR sensors and realize the application of SAR technology. Among them, since airports are extremely important strategic targets in the military, the detection of SAR airport targets is a very important technical means for military strikes and reconnaissance. [0003] At present, SAR airport detection methods are mainly divide...
