| 摘 要： | 面对现代战争的超视距要求,需要通信侦察装备具有很高的侦测灵敏度,尤其是侦测各种天波、散射及旁瓣信号。为此,提出将数字波束形成算法与比幅测向相结合,在空域与频域同时处理阵列信号,以此来提高系统的测向灵敏度和测向精度,仿真结果表明该方法要明显优于相位干涉仪测向法。

| Abstract: | According to the over_the_horizon demand, especially for the ionosphere, scatter and sidelobe communication signals, the reconnaissance equipments must have a high receiving sensitivity and accuracy. So, this paper proposed a new direction finding method which combines digital beam forming and amplitude comparison. In this way, the accuracy and sensitivity of direction finding were prompted. The results of numerical simulation showed it outperforms phase interference. |
