| 摘 要： | 提出了时空相关复合高斯分布海杂波下步进频雷达运动目标参数估计的方法.根据复合高斯分布杂波的散斑分量与纹理分量的分布特性,推导出步进频体制高分辨雷达的运动目标距离与速度的最大似然估计;提出目标误差函数的定义,基于目标误差函数最小化的准则,通过对距离进行搜索找到距离的估计值,并通过距离的估计值,求解出速度的最优最大似然估计值.仿真实验表明,该方法可以有效地估计出时空相关复合高斯分布海杂波背景下的步进频运动目标距离与速度参数.

| Abstract: | A new method to estimate the moving target parameters for high range resolution stepped frequency radar under temporal-spatial correlated compound Gaussian distributed sea clutter is proposed.Based on the distributions of the texture and speckle components of the compound Gaussian distribution,the maximum likelihood(ML) estimations of the target range and velocity are deduced and the definition of the target error function(TEF) is brought forward.Based on the principle of minimum TEF,the estimation of the t... |
