摘要
音频识别是塔康机载设备的一个重要功能指标。早期的塔康机载设备都是通过硬件输出模拟的识别音来实现的。为了增强识别信号的实用性和使用的方便性,本文提出了一种基于FPGA可编程逻辑器件的数字化译码方法,实现了塔康机载设备输出模拟识别音和ASCII码形式的识别码。
Audio identification is an important functional index of TACAN airborne equipment.Early TACAN airborne equipment is realized by hardware output analog identification sound.In order to improve the practicability of identification signal and convenience of use,a digital decoding method based on FPGA programmable logic devices is proposed,and the outputs of analog identification sound and ASCⅡidentification code for TACAN airborne equipment are realized.
