摘要
研究了空管系统中1090ES脉冲信号交叠问题的解决途径。讨论了利用Wigner-Ville分布(WVD)时频分析解脉冲交叠的可能性,提出了二次拐点法从时域上分离2个交叠脉冲的方法。仿真结果表明,二次拐点法适用于多种交叠情况。
An approach of 1090 ES signal overlapping problem of air traffic control system is proposed.Wigner-Ville distribution（WVD）time-frequency analysis is discussed to solve the overlapping problem.A method based on second-order inflexion is presented to separate the two overlapping signals in the time domain.Simulation results show that the second-order inflexion method can be applied to multiple overlapping conditions.
