Paper Abstract

Optimal trade-off filters for the Signal-to-Noise Ratio, the sharpness of the correlation peak and the optical efficiency are discussed. A unified formalism is introduced for Circular Harmonic (CH) and Synthetic Discriminant Function (SDF) filters. With this formalism, new solutions for CH and SDF filters are derived.
