A method of formulating ternary-valued (-1,0,1) correlation filters based on the ratio of spectral energies of target and nontarget patterns is proposed, and performance of such filters is investigated by computer simulations of correlation. The results confirm the intuitive expectation that such filters can enhance signalto- clutter and discrimination(More)

The basic design elements of binary phase-only filters (BPOFs) include the angle of a thresholding line in the complex plane and the offset from a center reference point of the pattern transformed in constructing the filter. These factors are analyzed, and a general formalism for the threshold-line angle variation is presented and related to the special(More)
