Abstract

This is the second paper in a series of articles devoted to modern methods of protection of coherent-pulse radars against the combined interference (i.e., an additive mixture of internal noise, masking clutter and noise jamming). Quantitative analysis of the influence of decorrelating factors on the efficiency of sequential adaptive systems with separate space-time signal processing (STSP) against the background of combined interference has been performed under conditions when the spatial processing with noise jamming compensation precedes the inter-period processing with clutter compensation. The analysis-based values of energy losses during the fluctuations of the random estimate of the spatial processing weight vector obtained for each sounding period over the limited size classified sample of noise jamming confirm the need to fix (store) this vector for the period of the inter-period clutter compensation. It is shown that the additional lack of classification of the training sample of interference increases the energy losses.

保护相干脉冲雷达免受组合干扰。2. 去相关因素对自适应序列STSP效率的影响分析

摘要

这是一系列文章中的第二篇文章，这些文章致力于保护相干脉冲雷达免受组合干扰（即内部噪声、掩蔽杂波和噪声干扰的加性混合）的现代保护方法。在噪声干扰补偿的空间处理先于周期间处理的条件下，定量分析了去相关因素对组合干扰背景下具有分离时空信号处理（STSP）的序列自适应系统效率的影响。杂波补偿。在有限大小分类的噪声干扰样本上，在每个探测周期获得的空间处理权重向量的随机估计波动期间基于分析的能量损失值证实了在期间杂波补偿。结果表明，额外缺乏对干扰训练样本的分类会增加能量损失。
