We have compared performances of a "minimum mean square error" filter matched to amplitude and phase encoded objects. We show that in the case of phase encoded objects the filter provides better discrimination capability. The correlation peak value obtained with the new filter is less sensitive to errors in noise statistics parameter estimations used to calculate the filter.
