| 摘 要： | 在哈达码变换成像光谱仪中,哈达码解码是非常重要的,其中噪声对解码又带来一定的影响.介绍了哈达码变换成像光谱仪的基本原理,在此基础上重点分析了用逆滤波法对哈达码解码的算法.在实际的成像过程中,由于会不可避免地引进噪声,通过分析,初步研究了高斯模糊噪声对哈达码解码算法的影响,并给出了计算机仿真结果,对于进一步研究哈达码解码算法具有重要意义.

| Abstract: | In the Hadamard transform imaging spectrometer,the Hadamard decoding is very important,and the noise brings an affect on the decoding to a certain extent.The basic principles of the Hadamard transform imaging spectrometer are described.On this basis,the inverse filtering method for Hadamard decoding algorithms is analyzed.In the actual imaging process,the noise will be inevitably introduced.Through analysis,the impact of the Gaussian blur noise on the Hadamard decoding algorithm is primarily studied,the computer simulation results are given.It is very important for the further study of Hadamard decoding algorithm. |
