在现代高分辨力雷达中,非高斯环境中的杂波对消问题显得越来越重要,因为杂波统计特性的不定性。为了评价动目标显示对消器的性能,本文对一种中频模型作了研究,在视频中,该模型给定一个具有对数正态概率密度函数的信号。文中还对多杂波环境中取得最佳检测性能所需的改善因子进行了估值。
In modern high-resolution radars, clutter cancellation in non-Gaussian environments is becoming more and more important because of the uncertainty of clutter statistics. In order to evaluate the performance of moving target display canceller, this paper studies a medium frequency model, which gives a signal with log normal probability density function in video. The paper also evaluates the improvement factors needed to achieve the best detection performance in multi-clutter environments.
