Rotation Invariant Amplitude Phase Composite Circular Harmonic Filter
The rotation invariant amplitude phase composite circular harmonic filter (CHF) is proposed. It gives an amplitude spectrum as the inverse of a biased amplitude spectrum of the CHF, and a phase spectrum as the phase spectrum of the CHF. Computer simulation results show that the proposed filter yields a sharper correlation peak, higher signal to noise ration and better correlation discrimination compared with the CHF and the phase only CHF.
