摘要
针对线性相位滤波存在的适用范围有限、计算量大等缺点，提出了采用多种线性相位组合来构建非线性相位，从而逼近真实相位的非线性相位滤波技术。处理结果表明，该方法较线性相位滤波方法更能保持条纹细节，并且有很高的计算效率。
The linear phase filter method has limited applicability and requires too much computing time. In order to solve the problems, the paper presents a non - linear phase filter algorithm that can approach the real phase by constructing non - linear phase with different linear phases combination. The results show that the algorithm of non - linear phase filter can effectively preserve phase details than linear phase filter and achieve greater computing efficiency.
