| 摘 要： | 基于动态规划的检测前跟踪方法可用于检测跟踪低可观测目标。它利用检测前跟踪的技术在检测目标的同时给出目标航迹的优点,实现对低信噪比下目标的检测与跟踪。本文分析了动态规划法进行弱小目标检测的基本原理,结合水下目标检测的特殊性对该算法进行了修正,得到了适应水下目标的检测前跟踪方法。通过实际的海试数据进行验证,证实了检测前跟踪技术在水声领域进行目标检测跟踪的可行性。

| Abstract: | The dynamic programming(DP)algorithm,using the advantage of the track-before-detect giving the track while detecting the target,is used to detect and track low-observable targets under low signal-to-noise ratio(SNR).In this paper the fundamental principles of the DP is formulate,then we modify it and make it useful in passive sonar signal processing.Finally we prove it practically in passive sonar for targets detecting and tracking after testing it using the data from real marine environment experiment on a linear array. |
