小波变换在无线电引信中的应用

本文充分利用小波的极大模特性可以检测出奇异信号的特殊功能，对无线电引信的信号进行分析。应用多尺度模极大值，去除引信信号噪声，提高引信测量精度，采用无线电引信机发射脉冲宽度随机可变措施，区分真假回波，再根据其能量大小，辨别真假目标；用记录各种尺度下模极大值坐标，代替无线电引信记录整个过程，起到压缩数据目的，这些数据包含无线电引信的主要信息，经实验表明，此方法是可行的。

APPLICATION OF WAVELET TRANSFORM IN RADIO FUSE

This paper analyses radio fuse signals using the wavelets as the mathematical microscope which has the special function of singularity signals. The wavelet transform maximum is used in order to cancel noises in the fuse signal and improve the precision of the fuse machine. The stochastic variable measure of the pulse breadth emitted by the radio fuse machine is used in order to distinguish the reality of the echo. The reality of the object is identified according to the size of the echo energy. The maximum coordinate of different kinds of scale is used replacing the whole processing of radio fuse recording. So, compression of data is attained. These data include the main information of radio fuse. The idea is practicable as can be seen from the results of the experiments.
