本文通过对杂波实测数据的处理,利用高斯分布模型、指数分布模型、幂指数分布模型及高阶AR等分布模型,得到了双基地雷达前向散射地表杂波概率分布和功率谱分布的数学模型;并从统计理论上解析地推导了杂波统计模型对目标检测性能的影响.基于估计的概率分布、功率谱分布数学模型及广义匹配滤波理论,实现了前向散射地表杂波的有效抑制与目标运动参数的精确估计,并利用实测数据进行了验证.
In this paper, we get the mathematics of probability distribution and power spectrum distribution of forward-scattered surface clutter of bistatic radar by processing the measured clutter data and using Gaussian distribution model, exponential distribution model, exponential distribution model and high-order AR equal distribution model Model and the influence of clutter statistical model on target detection performance is analytically derived from statistical theory.According to the estimated probability distribution, power spectral distribution model and generalized matched filter theory, the effective suppression of forward-scattered surface clutter With the accurate estimation of the target motion parameters, and verified with the measured data.
