摘要
介绍了几种典型的计算全息匹配滤波器的制作原理,并且在此基础上提出了二元振幅补偿型匹配滤波器,通过计算机模拟,比较了它们的匹配识别效果。研究表明,二元振幅补偿型匹配滤波器在相关峰高度及尘锐度、鉴别率、抑噪能力等方面都超过了其它几种匹配滤波器。
The principle of making some typical matching filters by computer-generated hologram is introduced,based on this we propose binary amplitude-compensated filters.The computer simulation result shows this filter’s performance of correlation peak value,correlation peak acuity and discrimination are better than other kinds of matching (filters.)
