摘　　要：针对天基广域探测系统复杂背景下红外运动目标稳定探测的问题,提出一种应用探测检测一体化设计的红外运动目标增强方法。利用双向过采样探测方式,每次扫描探测均可实现对运动小目标90%以上能量收集;在检测过程中,通过相邻扫描图像帧的配准与差分计算,进行强背景杂波抑制,背景杂波强度平均可降低90%以上;结合双向过采样探测传递模型,采用全变分约束构建去噪复原模型,进行目标增强与噪声抑制一体化处理,在实现目标能量集中度提升的同时抑制噪声,差分图像中目标信噪比可进一步提升优于2.5倍。试验结果表明:通过探测检测一体化设计,可以有效实现红外运动目标增强,提升对红外运动目标的探测能力。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 bidirectional 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 suppression 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 oversampling detection transfer model,a denoising and restoration model is constructed using total variation 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.
