Abstract : This report examines the requirements for performing Electronic Warfare Support Measures (ESM) on VHF/UHF facsimile transmissions in the tactical environment. A complete description of the CCITT Group III recommendations is given. These specifications apply to over ninety percent of the facsimile machines currently in use. Both modulation techniques and image encoding formats are discussed thoroughly. A description is then given of the HIGHWIRE system. HIGHWIRE is a communications Electronic Warfare Support Measures System which has been developed in the Electronic Warfare Division at the Defence Research Establishment Ottawa to investigate the feasibility of tactical facsimile ESM. Current capabilities of the system are described, and future work is discussed.
