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。In locating the uplink interference to geostationary earth orbit（GEO） satellites,complex analysis work often takes hours of time. For burst and short time interferences,it always misses the best location opportunity,so as to cause a very high fai l probability for locating these signals. To settle the delay problem, an automatic location scheme is proposed which includes quantitative and qualitative analysis for neighbor satellite choosing,location scheme design and reference signal choosing and transmitting. Experiments prove the feasibility. This scheme makes it possible for a machine to replace manual analysis and is helpful for quick and accurate interference transmitter location.
