-
摘要: 文中在概要介绍毫米波焦平面阵列成象探测器中存在的1/f 噪声的特性的基础上，深入分析了小波变换与1/f 噪声的关系，提出用小波分解的方法对毫米波焦平面探测器的1/f 噪声进行去相关处理，推导了相应的表达式。仿真结果表明可得到满意的效果。Abstract: After briefly interoducing the characteristics of 1/f noise in millimeter wave focal plane array detectors, the paper analyses the relation of the wavelet transform and 1/f noise in detail and suggests the fashion of decorrelating 1/f noise using the wavelet transform., also deduces the relative expressions. The results of computer simulation show the good effect.
