为提高干扰的有效性和针对性, 解决全向天线发射干扰信号干扰效率低且会对民用和己方电子系统造成干扰的问题, 考虑使用阵列天线发射干扰信号。基于LCMV波束形成准则, 分别采用多权值矢量和单权值矢量形成多波束, 并对这两种波束形成方法进行了仿真比较。仿真结果表明, 使用阵列天线进行波束形成, 单权值矢量在干扰波束宽度, 干扰波束最小间隔以及主副瓣功率差值分别有2°, 4°和4 dB的优势。

In order to improve the effectiveness and pertinence of TACAN jamming, and solve the problem that the jamming signals may disturb the civil signals and the own electronic systems, it is proposed to transmitte the jamming signals by array antenna. Based on the LCMV rule, the signals inputed to arrays are multiplied by multiple weight vectors and single weight vector respectively, and the two beam'forming methods are analyzed by simulation. The simulation results show that, when using array antenna for beam forming, the single weight vector has 2 degrees, 4 degrees and 4 dB advantages respectively in such aspects of half'power beam width, minimum spacing of the beam and power difference between the main lobe and the sidelobe.
