基于无人机的炮位侦校雷达目标模拟技术

A Target Simulation Technology for Artillery Reconnaissance and Fire-directing Radar Based on UAV

雷达目标模拟技术广泛应用于雷达研制、生产和日常训练维护,受技术条件限制,常规的目标模拟器只能模拟目标的径向运动,不能模拟目标的角度变化。以炮弹目标模拟器为例,介绍了基于无人机的炮位侦校雷达目标模拟器的工作原理,根据不同炮弹运动轨迹的特点,推算出对无人机位置变化的控制需求。研究了串级比例、积分、微分(PID)控制技术、模糊PID控制技术和基于变论域模糊PID控制技术,并以典型四旋翼无人机为例,对这3种控制方法进行了仿真分析,从位置响应曲线和姿态响应曲线可以看出,采用上述3种控制技术,无人机各控制量均能达到预期的稳定状态,只有采用变论域模糊PID控制技术可以满足控制系统的使用要求。

Radar target simulation technology is widely used in radar development,production and daily training&maintenance.Due to technical condition limitations,the conventional target simu-lator can only simulate the radial motion of the target and cannot simulate the angle change of the target.Taking the artillery target simulator as an example,this paper introduces the working prin-ciple of the artillery reconnaissance and fire-directing radar target simulator based on unmanned aerial vehicle(UAV).According to the characteristics of the motion trajectories of different artil-lery projectiles,the control requirements for the position change of UAV are calculated.Cascade proportional-integral-derivative(PID)control technology,fuzzy PID control technology and varia-ble universe fuzzy PID control technology are studied.A typical quad-rotor UAV is taken as an ex-ample for simulation analysis using these three control methods.From the position response curve and altitude response curve,it can be seen that the UAV control parameters can reach the expected stable state by using the above three control design approaches.Only variable universe fuzzy PID control technology can satisfy the implementation requirements of control system.
