摘要/Abstract

摘要： 针对现有宽带数字波束形成方法在雷达干扰技术领域的工程应用中存在适用信号单一、干扰效果差、实现难度高等缺点，采用一种基于2阶锥规划(SOCP)理论的雷达干扰宽带数字波束形成方法，在波束形成器的每个阵元通道各自使用1个对应的宽带有限长单位冲激响应滤波器对待发射宽带干扰信号进行整体幅相调制。为获得最佳滤波器系数，采用线性约束最小功率准则对波束形成器进行设计及优化。通过消除旁瓣约束式的频率依赖性，并将滤波器系数求解问题的解析形式转化为相应的SOCP形式，降低了优化难度。仿真结果表明，该方法可以较好地解决相应约束条件下雷达干扰宽带数字波束形成优化设计问题。

Abstract: The present wideband digital beamforming method has some disadvantages in engineering application of radar jamming, such as single applicable signal, poor jamming effect and high implementation difficulty. A wideband digital beamforming method for radar jamming based on second-order cone programming (SOCP) theory is adopted. The amplitude and phase of wideband jamming signal are modulated using a corresponding wideband finite impulse response filter in each channel of beamformer. In order to obtain the best filter coefficient, a linear constrained minimum power criterion is adopted to design and optimize the beamformer. The optimization difficulty is reduced by eliminating the frequency dependence of side lobe constraint and transforming the analytical form of filter coefficient solution into the corresponding SOCP form. The simulated results show that the proposed approach can be used to solve the optimal design issue. Key
