[0002] In modern warfare, the land battlefield will face more and more threats from miniaturized and intelligent weapons and equipment. Various camouflaged targets, stealth targets, drones and other targets are becoming increasingly difficult to detect, especially when the targets adopt stealth / camouflage technology, or are affected by bad weather such as rain, snow and fog, they mainly appear as "weak feature" targets, making it more difficult to accurately detect them.

[0003] Traditional optical imaging detection technology mainly uses the difference in information such as intensity / spectrum between the target and the background to achieve target detection. The intensity imaging technology equipment has a simple structure and a very high frame rate, but it cannot reflect the difference in spectral characteristics and it is difficult to overcome the adverse effects of background interference; spectral imaging technology can obtain information from different spectral bands and can accurately reflect the difference between the target and the background, but this technology equipment has a complex structure, a large amount of data, and a low frame rate, making it difficult to image dynamic targets in real time. "Weak feature" targets are difficult to detect from the background because of the small difference in their characteristic signals from the background. In addition, the movement of aerial targets makes detection difficult.
