| 摘 要： | 离散余弦变换是分析图像信号的有效工具。应用航天部二院提供的ISAR外场实测数据,做出Yak 42飞机回波的一维距离像,采用离散余弦变换分析了高分辨雷达距离像的频谱特性。并与离散傅里叶变换进行了比较和分析。用Matlab对结果进行仿真,结果表明用DCT是分析和处理雷达信号的一种有效方法。

| Abstract: | Discrete Cosines Transform(DCT) is an effective tool for analysis image signal.This paper uses the ISAR outfield substantive data sets provided by spaceflight ministry second department.The HRRP of Yak42 is made,and the spectrum characteristic of high resolution range profile is analysed by disperse cosines transform,comparing with discrete Fourier transform.Result of computer simulation by Matlab demonstrated it is effect to analysis and preprocess radar signal by discrete cosines transform. |
