Investigation of Using the Walsh Transform for Deinterleaving Simulated ESM (Electronic Warfare Support Measures) Receiver Output

Abstract

The Walsh Transform is investigated for its usefulness in deinterleaving the interleaved pulse stream presented to a preprocessor by an ESM (Electronic Warfare Support Measures) receiver. After background chapters on a typical ESM system and the theory and characteristics of the Walsh Functions, a number representation of the pulse stream is described. Fast Walsh Transforms and Power Spectral Densities of the pulse representations are computed and analyzed for features that could be used to recognize individual pulse trains in the interleaved representation.
