摘　　要：针对GPS单站干扰距离短、干扰范围小的问题,研究了GPS多站干扰效能.首先给出了不同压制性干扰信号影响下GPS信号的误码率计算,根据通信干扰效果评估准则,推导了GPS单站干扰方程和多站干扰方程,然后对布站方式分别为线形、环形、梯形时的干扰压制区进行了仿真.仿真结果表明,误码率为0.12时,四种压制性干扰的单站干扰压制区范围由大到小依次为噪声调幅干扰、射频噪声干扰、噪声调相干扰和噪声调频干扰;干扰站数量相同时,最大干扰距离由大到小依次为环形布站、梯形布站和线形布站,干扰压制区宽度由大到小依次为线形布站、环形布站和梯形布站.Aimed at the problem of a single GPS jammer’s small jamming range, the paper conducts aresearches on multiple GPS jammers’efficiency. Firstly the paper calculates the error rate of GPS signal underdifferent blanket jamming signals. And then based on the evaluation criterion of communication jamming effect,the paper deduces the single jammer interference equation and the multi-jammers interference equation. Finallythe paper simulates the blanketed zone when the modes of jammers deployment are of linear distribution, ringdistribution and trapezoidal distribution. The simulation results show that the range of a single jammer’sblanketed zone of four kinds of suppressive jamming ranks descending from noise AM jamming, RF noisejamming, noise PM jamming to noise FM jamming. When the number of jammers is the same, the descendingorder of jamming range is from ring distribution, trapezoidal distribution to linear distribution. The widestblanketed zone is of linear distribution, and the next is ring distribution, and trapezoidal distribution.
