Paper Abstract

Law probability of intercept (LPI) surveillance and communication systems can be of vital benefit to a number of military applications. The basic concept in all LPI systems is to spread the transmitted power over as wide a frequency band as possible to make detection as difficult as possible. The critical technology issue involved in implementing this concept is to achieve complex real time matched filter signal processing in the receiver with as large a processing gain as possible. This paper briefly discusses an experimental program, which combined a surface wave tapped delay line and optical coherent integrator to demonstrate processing gains on the order of 70 dB; and the evolving technology in optical signal processing, which needs to be developed to achieve feasible systems application.
