摘　　要：为了提高平台侦察的灵敏度以及释放干扰时自身的隐蔽性,提出一种基于多载波频率分集阵列(FDA)的侦察-干扰一体化平台。频控阵相较于单个天线具有更高的测频精度和抗噪声性能,并通过调整相关参数,可以干扰不同体制雷达。首先建立阵列接收的波束模型;然后从单天线测频的原理出发,论证和仿真频控阵基于Root-MUSIC算法的优势;最后分析针对不同体制雷达的频控阵干扰方式。理论分析与仿真结果表明,上述方法具有更高的侦察精度和更丰富的干扰方式。In order to improve the sensitivity of the reconnaissance platform and the concealment when the interference is released,an integrated reconnaissance-interference platform based on multi-carrier frequency diversity array(FDA)is proposed.Compared with single antenna,FDA has higher frequency measurement accuracy and anti-noise performance,and the different system radars could be jammed by the relevant parameters.Firstly,the beam model of array receiving is established.Then the advantages of frequency array based on root-music algorithm are demon-strated and simulated.Finally,the scheme of frequency array signal jamming against different ra-dar systems is analyzed.Theoretical analysis and simulation results show that the above method has higher reconnaissance precision and more efficient jamming scheme.
