摘要
针对现代低功率发射和大时宽、高工作比体制雷达工作时受到的同型临近雷达干扰或敌方欺骗干扰,分析和仿真了雷达间主瓣与主瓣、主瓣与副瓣和副瓣与副瓣的同频干扰及其对雷达的目标回波功率、信号频谱、探测概率和信噪比等方面影响所表现出来的特征,给出了同频干扰对雷达接收机前端的损伤分析结果,为雷达抗同频干扰技术和方法研究提供必要的理论和分析基础。
The jamming from nearby radars with the same model or the enemy deception jamming is received by the working modem radars with low power, large time width and high duty ratio, in terms of which the common-frequency jamming between radar main lobes, side lobes, main and side lobes, and the characteristics resulting from its effects on the target echo power, spectrum, detection probability and SNR are analyzed and simulated. Besides, the signal frequency damage analysis results of the front-end of radar receiver are given to provide indispensable theory and basis for the common-frequency jamming resistance technology and method analysis
