Abstract
In response to the problem of stable detection of infrared moving targets in the complex background of space-based wide area detection system,an infrared moving target enhancement method based on the integrated design of detecting and processing is proposed.By using the bidi-rectional oversampling detection mode,more than 90%of the energy of the small moving target can be collected in each scanning.During the detection process,strong background noise suppres-sion can be performed by registering and subtracting adjacent scanned image frames.The average background clutter intensity is reduced by more than 90%.Combining the bidirectional oversam-pling detection transfer model,a denoising and restoration model is constructed using total varia-tion constraints.The integrated processing of target enhancement and noise suppression is carried out to improve the energy concentration of the target while suppressing noise.The signal-to-noise ratio of the target image is further improved by more than 2.5 times.The experimental results show that the method of integrated design of detecting and processing can effectively enhance the infrared moving target and improve detection capability of the infrared moving target.关键词
