摘　　要：为提升复杂电磁环境中不同噪声干扰和不同信号幅度下的战术空中导航系统(Tactical Air Navigation System, TACAN)信号检测性能,提出一种新的自适应门限的TACAN信号检测技术,该技术采用自相关和互相关的方法分别计算信号检测门限以及滤波后的信号,不仅实现了不同噪声、不同信号幅度下的TACAN信号自适应检测,而且非常方便和准确地进行TACAN脉冲宽度、间隔等参数的测量。经仿真验证,该技术具备良好的TACAN信号检测性能。In order to improve Tactical Air Navigation System(TACAN)signal detection performance under different noise interference and different signal amplitudes in complex electromagnetic environment,a new adaptive threshold TACAN signal detection technology based on complex environment is proposed.The technology uses the autocorrelation method to calculate the signal detection threshold,and uses the cross-correlation method to achieve signal filtering,which not only realizes the adaptive detection of TACAN signals under different noises and different signal amplitudes,but also conveniently and accurately measures the parameters such as TACAN pulse width and interval.The simulation result proves that proposed technology has good TACAN signal detection performance.
