Abstract : A method and circuit for performing coherent integration on a signal output from a conventional signal processing circuit's detector/averager is presented. The post-processing coherent integrator is designed to be inserted in a conventional signal processing circuit between the detector/averager circuit and the threshold detector circuit. A digital form of the post processing coherent integrator comprises a sample-and-hold circuit to receive a signal output from the detector averager of the conventional signal processing circuit, an analog to digital converter, a delay and multiplier circuit, a memory circuit for storing weighting constants, a Summer circuit, and an output to a conventional signal processing system's threshold detector and display.
