摘要
天线是通信对抗系统的关键组成部分,其性能直接影响整个系统的作战效能。采用时域有限差分法(FDTD)分析无人机的机载VHF干扰天线,计算了天线的辐射方向图。以干扰有效压制区作为无人机通信干扰能力的评估指标,提出了一种计算无人机处于任意姿态时的地面干扰有效压制区的方法。计算结果证明了该方法的可行性和有效性。
Antenna is an essential component of communication countermeasure system, and its performance directly affects the whole system's combat effectiveness. FDTD method is used to analyze the VHF jamming antenna of the communication countermeasure UAV and the radiation pattern is calculated. The communication suppressing zone is introduced to evaluate the jamming capability of the UAV and a new method is proposed to calculate it while the flight attitude is facultative. The simulation results prove the method's feasibility and validity.
