摘要
研究了两种方位/频率目标运动分析算法:最大似然法和伪线性法,并基于这两种算法构成了一个实时实验系统。实验研究表明充分利用伪线性解的解析性和最大似然解的最佳性可以对辐射噪声中含有窄带分量的匀速直线运动目标进行最佳的无源估距,且无需本艇机动并具有稳定性好、收敛性快的优点。
Two algorithms of bearing/frequency target motion analysis are studied, which are maximum likelihood method and pseudo-linear method. Based on these algorithms we have implemented a real-time experimental system. The experiment indicates that fully utilizing benefits of two methods can optimally localize moving target which radiates narrow-band noise and need not own-ship maneuver.
