摘　　要：随着空间卫星通信技术的发展,电磁环境日益复杂,信号在传输过程中更加容易受到干扰,从而导致出现了更多的安全问题,因此对卫星干扰源实现高精度定位具有十分重要的意义。为了解决干扰源定位问题,构建了合理的无源定位数学模型进行深入研究,设计了一种优化的单站定位方法,并且综合分析了卫星转发时延、卫星经纬度等误差因素以实现优化。最后通过仿真试验,验证了该方法的有效性和定位精度。Due to the development of space satellite communication technology,the electromagnetic environment becomes increasingly complex and the signals are more susceptible to be jammed during transmission,which leads to more security problems.Therefore,it is of great significance to achieve highprecision positioning of satellite jamming sources.To address the jamming source positioning problem,this paper builds a reasonable mathematical model of passive positioning for in-depth study,designs an optimized single-station positioning method,and comprehensively analyzes the error factors such as satellite forwarding delay,satellite longitude and latitude to achieve optimization.Finally,simulation results indicate that the method is effective and accurate in positioning.
