摘　　要：针对杂波背景下末制导雷达微弱目标检测问题,提出一种基于微动滑窗的敏捷长时混合积累方法。长时相参积累是一种有效的微弱目标检测方法,但是此类方法需要大量的参数搜索,不适用于弹载末制导雷达实时性的问题,将长时间相参积累分为短时MTD处理和长时PRT变换的非相参积累处理,解决现有长时间相参积累计算量大的问题。针对制导系统的数据率要求,进一步提出利用微动滑窗完成数据的边积累边输出,满足末制导雷达输出数据率的需求。仿真和实际数据验证证明了方法的可行性和优越性。An agile long-term hybrid accumulation method based on micro sliding window is proposed for detecting weak targets in terminal guidance radar under clutter background.Long term coherent accumulation is an effective method for detecting weak targets,but this type of method requires a large amount of parameter search and is not suitable for the real-time performance of missile borne terminal guidance radar.Long term coherent accumulation is divided into short-term MTD processing and long-term PRT transformation non coherent accumulation processing to solve the problem of large computational complexity in existing long term coherent accumulation.In response to the data rate requirements of guidance systems,furthermore,it is proposed to use a micro sliding window to achieve edge accumulation and output of data,meeting the demand for output data rate of terminal guidance radar.Simulation and actual data verify the feasibility and superiority of the method.
