摘　　要：研究了干扰对塔康系统的性能影响问题。首先,基于塔康系统在射频噪声压制干扰和饱和询问干扰下有效导航区域计算模型分析了单干扰器和多干扰器对信标台导航区域半径的影响;其次,研究了同频和异频包络干扰对测角精度的影响;最后,对分析结果进行了仿真验证。仿真分析表明,多干扰相对于单干扰能更加有效地影响信标台的导航区域,饱和询问式干扰比射频噪声压制干扰效果好,同频和异频包络干扰均会导致精测区间出现错误,实现40°的测角误差。The influence of jamming on the performance of TACAN system is studied.Firstly based on the models of effective navigation area under the blanketing jamming of radio-frequency noise and saturated asking jamming the influence on the radius of effective navigation area of the beacon station under the action of single jammer and multiple jammers is analyzed.Secondly the error of angle measurement under the envelope jamming of the same frequency and of different frequencies is deduced.Finally the analysis results are verified by simulation.The simulation results show that:(1)Multiple small-power jammers are more effective in affecting the navigation area of the beacon station than the single large-power jammer;(2)The saturated asking jamming is better than blanketing jamming;and (3)The envelope jamming of the same frequency and of different frequencies will cause the error in accurate measurement interval and about 40°angle measurement error will occur.
