中文摘要:

      无人机凭借其灵活性高、操作简便且可搭载多种设备的优势，在雷达标校和测试中的应用日益广泛。鉴于多普勒雷达在动态测试和跟踪方案验证方面存在不足，设计了一种集成无人机与动态模拟源的天地闭环推演系统。该系统通过无人机的航迹规划模拟目标飞行轨迹，同时利用动态模拟源模拟雷达接收到的目标信号特征，实现目标飞行和信号变化的联合仿真。实际应用表明，该系统能够实现多普勒雷达的性能测试、理论数据推演和历史数据复演。

英文摘要:

      Unmanned aerial vehicles（UAVs） are widely used in radar calibration and testing due to their high flexibility,easy operation,and the ability to carry a variety of equipment.In view of the shortcomings of Doppler radar in dynamic testing and tracking scheme verification,a closed-loop deduction system integrating UAV and dynamic simulation sources is designed.The system simulates the target flight path through the UAVs flight path planning and simulates the target signal characteristics received by the radar using the dynamics simulation source to realize the joint simulation of target flight and signal changes.Practical applications show that the system can achieve performance testing,theoretical data deduction,and historical data reconstruction of Doppler radar.
