Space-time interference suppression technology of satellite navigation receiver

  • 摘要: 卫星导航用户机在多个干扰源(包括宽带和窄带)或导航信号和干扰信号空间角谱接近的情 况下,系统定位精度降低甚至无法满足定位要求.为此提出具有方向约束条件的改进联合空 时处理算法,将干扰源来向检测和获取的导航卫星信息作为条件约束判据引入联合空时滤波 处理算法,在抑制干扰信号的同时使靠近干扰源来向的卫星信号正常接收.仿真表明,在有 限阵元规模情况下,保证干扰信号的高抑制度(大于40 dB),并提高干扰抑制自由度,最 重要的是当导航卫星信号与干扰信号的空间角谱接近时(10°左右),在部分区域内有效抑 制干扰的同时接收机仍然能够正常工作.该算法在一定程度上提高区域导航卫星系统在复杂 电子环境下的抗干扰能力.
