Abstract

The phase values in binary phase only filters cannot be directly calculated to give the highest correlation peaks. We show the condition for which the optimum binary phase is it,and the condition for which it is not it.Computer simulation shows that for a BPOF encoded with the simulated annealing algorithm, its binary phase is other than iv andthe correlation peak of a given pattern is increased by more that 35%, compared with the correlation peaks of the BPOFs encoded by the conventional methods.
