针对舰载无人机挂载电子侦察载荷对辐射源目标进行无源测向的问题,在对舰载无人机无源测向原理分析的基础上,建立了无源测向精度计算模型,探讨了误差的主要来源,通过仿真得到了舰载无人机无源测向时飞行姿态的控制要求,为驱护舰编队作战中舰载无人机进行无源测向提供了理论与方法。 Aiming at the problem of passive direction finding of the radiation source target by the electronic reconnaissance payload mounted by the shipborne UAS, the passive direction finding accuracy calculation model of the carrier UAV is established based on the analysis of the principle of passive direction finding. The main source of error is discussed. The flight attitude control requirements of the shipborne UAV during passive direction finding are obtained through simulation. The theory and method are provided for the passive direction finding of the shipborne UAV in the defense of the frigate.
