PROBLEM TO BE SOLVED: To solve the problem in which inherent limitations to amplitude matching may limit performance of a system including a matched filter.SOLUTION: A photonic match filter comprises: a first optical arbitrary phase waveform generator adapted to accept a coherent light signal and apply a first temporal phase shift pattern to the coherent light signal; a second optical arbitrary phase waveform generator configurable to receive an output signal of the first optical arbitrary phase waveform generator and apply a second temporal phase shift pattern to the output signal; and a propagation path configured to propagate the coherent light signal from an output of the first waveform generator to an input of the second waveform generator. The second temporal phase shift pattern has time delay with respect to the first temporal phase shift pattern.
