| 摘 要： | 干扰的存在性检测是对抗拖曳式诱饵干扰的前提和基础，也是决定抗干扰效果的重要因素。本文在对拖曳式诱饵干扰原理、过程样式以及性能特点进行系统分析的基础上，详细描述了雷达波束内诱饵存所带来的角闪烁效应。基于已有关于不可分辨目标检测的研究结论，结合拖曳式诱饵干扰对抗的特点，对角闪烁信息进行了特征提取，根据特征利用方式的不同分别给出了典型的拖曳式诱饵干扰场景下复角检测法、推广正交法和GLRT法3种诱饵存在性检测方法的检测判决式。在典型干扰场景以及条件下对检测方法进行了仿真验证。结果表明3种方法在一定程度上都能够正确检测诱饵的存在，其中GLRT方法具有最好的检测性能，是一种满足应用需求背景的有效的诱饵存在性检测方法。

| Abstract: | The detection of presence of the jamming is the precondition and foundation to counter the Towed Radar Active Decoy (TRAD) and it is an important factor of deciding the effect of ECCM.In order to solve this detection problem,the systemic analysis about the course,format and performance of the TRAD was given,and the angle glint phenomena due to the presence of the TRAD in the radar wave beam were described detailed.Based on the existent conclusion of detection of unresolved targets,the character of the angle... |
