摘要
由于相位编码雷达采用了相关处理技术,使得传统的干扰样式很难达到理想的干扰效果。为了有效干扰此种雷达,首先分析相位编码雷达信号的特点,然后通过理论分析和仿真验证的方式研究射频噪声干扰、部分复制干扰、移频干扰和基于DDS的相位编码干扰。仿真分析结果表明,射频噪声干扰对相位编码雷达的干扰效果较差,另外三种干扰样式则可在低干信比条件下达到很好的干扰效果。
Because of using correlation processing technology, phasecoded radar can not be effectively jammed by traditional jamming styles. In order to effectively jam this radar, characteristics of the phasecoded radar signal is firstly analyzed, then radio frequency jamming, part duplication jamming, shift - frequency jamming and phase - coded jamming based on DDS are studied by theoretical analysis and simulation verification. The results of simulation and analysis prove that radio frequency jamming is not effective and the other three jamming styles are effective in the case of low JSR.
