ABSTRACT

True phase including phase characteristic of different complex functions and transfer functions is calculated by applying modulo 2π operation to tangent inverse function. Tangent inverse function is value limited to -Π/2<x <Π/2 . Different artificial discontinuities or phase jumps appear in the phase function. The problem of phase unwrapping is considered here and a new phase unwrapping method for removing artificial phase jumps was described and tested. A quantitative study is made to compare modulo 2Π unwrapping algorithm with the proposed algorithm in this paper.


Keywords: Phase Unwrapping; Butterworth filter; SAR; modulo 2Π operation; recurrent al-gorithm.
