摘要
介绍发达国家和我国有关研究机构在分布式无源检测信息系统领域,利用电视、广播、移动通信基站等大量分布式设施作为辐射源实现目标的探测和定位的近期研究进展,具有重要的理论意义和实用价值.分析实现目标检测必须解决的关键技术,包括直达波抑制、参考信号提取、微弱信号检测、解距离模糊及实时信号处理等.针对分布式无源检测信息系统的特点,研究盲自适应检测融合算法和协方差交叉算法在目标检测和航迹融合中的应用.
Target detection and location are implemented in distributed passive detection system by using distributed establishments of TV , broadcast and mobile communication as illuminators. This technique is very significant and useful in both theory and practice. The recent research development of this field in the world is introduced at first, the key technical problems of target detection are then analyzed, which include the direct signal suppression, reference signal acquisition, weak target detection, distance ambiguity solution and real time signal processing. According to the characteristics of distributed passive detection system, the application of blind adaptive detection, fusion algonthm and covariance crossing algorithm in target detection and track fusion are studied.
