Abstract
A method is proposed for designing a distortion-invariant correlation phase-only filter by iteratively optimizing the Horner efficiency. Com parisons with conventional filters show some attractive properties of the proposed filters, such as a high correlation peak and good discrim ination ability. An effective improvement for reducing the peak deviat ion of the phase-only filter is also proposed. The correlation perform ance of the constructed filters is confirmed by computer simulation.
