Paper Abstract

We previously reported computer code designed to generate optical correlator filters by putting our optimization algorithm into practice. This code is MEDOF: Minimum Euclidean Distance Optimal Filter. MEDOF's version 1.0 demonstrated filters which maximize correlation peak intensity (INT). We also gave some discussion to the quadratic ratio metrics of signal to noise ratio (SNR) and peak to correlation energy ratio (PCE). These advanced metrics are now functional in the second version of MEDOF, which is publicly available through NASA's software distribution channel, COSMIC. This paper focuses on some of the practical issues faces when using MEDOF to generate filters. The underlying mathematical principles of MEDOF are discussed in passing while providing references to sources of more theoretical detail.
