反辐射导引头测向天线基线长度较短,导致测向精度有限。基于干涉仪测向原理,利用无人机编队实现长基线干涉仪测向系统构建,以提高对辐射源的测向精度。建立了测角误差计算模型,通过仿真分析了影响测角误差的主要因素,将长基线干涉仪测向系统与传统干涉仪测向系统测角误差进行了对比。仿真结果表明,解决高精度定位技术和多无人机监督控制技术等关键技术后,长基线测向系统测向性能与传统干涉仪测向系统相比有明显提高。 The baseline length of the anti-radiation seeker directional antenna is short, resulting in limited accuracy of the DF. Based on the principle of interferometry, the construction of long baseline interferometer direction finding system is realized by using the formation of unmanned aerial vehicles to improve the accuracy of the direction finding of the radiation source. The calculation model of the angle measurement error is established. The main factors influencing the error of the measurement angle are analyzed by simulation. The measurement error of the long baseline interferometer is compared with that of the traditional interferometer. The simulation results show that after solving the key technologies such as high-precision positioning technology and multi-UAV supervisory control technology, the DFG system’s DF performance is obviously improved compared with the traditional DFG system.
