摘要：

A method is proposed for designing a distortion-invariant correlation phase-only filter by iteratively optimizing the Horner efficiency. Comparisons with conventional filters show some attractive properties of the proposed filters, such as a high correlation peak and good discrimination ability. An effective improvement for reducing the peak deviation of the phase-only filter is also proposed. The correlation performance of the constructed filters is confirmed by computer simulation.
