Problems solved by technology

The classic constant false alarm detection only statistically models the background information, does not consider the complete modeling of the target information, only uses some features of the target imaging area to detect, does not make full use of the global features, and has a high false alarm rate; traditional feature extraction The method needs to consider information modeling or rule matching in a specific environment. However, in practical applications, th...

Description

technical field [0001] The invention belongs to the technical field of image processing and target recognition, in particular to a radar image target detection system facing typical active interference. Background technique [0002] Different from traditional optical images, the amount of information in radar images is seriously insufficient, and there are significant differences in imaging mechanism, target characteristics, and resolution. The imaging characteristics of radar echo data on the Doppler dimension are significantly different from those of optical images: the image contains a large amount of mixed active and passive noise such as clutter signals, and the pixel ratio of targets and interferers is extremely low compared to the entire image And the distribution is sparse. Traditional radar image target detection generally uses prior knowledge to extract features through candidate regions. The classic constant false alarm detection only statistically models the ba...
