【摘要】：在对静止轨道卫星上行干扰的定位过程中,复杂的分析工作往往需要花费数小时,当干扰信号为突发、短时类信号时,往往会错失定位时机,导致对这类信号的定位失败率非常高。为了解决静止轨道卫星干扰定位的滞后性问题,设计了一种针对静止轨道卫星干扰的自动化定位解决方案。对干扰定位工作中的邻星选择及定位方案设计、参考源信号的选择与发射等各关键环节进行了定量和定性分析,并通过仿真实验证明了该方案的可行性。该方案使得用机器代替人工分析成为可能,对卫星干扰源的快速和准确定位具有现实意义。
[Abstract]:In the process of locating the uplink interference of geostationary orbit satellite, the complex analysis work often takes several hours. When the jamming signal is burst and short-time signal, it will often miss the location opportunity. In order to solve the lag problem of geostationary orbit satellite interference positioning, the failure rate of this kind of signals is very high. An automatic positioning solution for geostationary satellite interference is designed, and the selection of adjacent satellites and the design of location scheme are also presented in this paper. The selection and transmission of reference signals are analyzed quantitatively and qualitatively, and the feasibility of this scheme is proved by simulation experiments. This scheme makes it possible to use machine instead of manual analysis. It has practical significance for fast and accurate location of satellite interference source.
