TACAN机载接收机谐波抑制对测距精度的影响研究

摘要

TACAN airborne receiver communicates with ground station over wireless channel. The wireless signals are received by airborne receiver over super heterodyne RF channel. The design of RF channel is of importance because the performance of the channels has a direct influence on TACAN distance measurement precision. Using a theoretical analysis, the influence of the harmonic inhibition of TACAN airborne receiver on distance measurement precision is provided for further reference of the RF channel design.%　　TACAN 机载设备通过无线信道与地面台通信，机载设备信号的接收是通过超外差射频通道进行的，通道性能的好坏直接影响TACAN 测距精度，所以射频通道的设计至关重要。本文正是基于这一点，通过理论分析的方法研究了TACAN机载设备射频通道指标中谐波干扰信号的特性对TACAN测距精度的影响，为TACAN射频通道的设计做出参考。
