<dd>This study consists of a performance evaluation of ship mounted COMINT systems collecting against VHF/UHF data/voice signals in a littoral environment. The detection range for each combination of collector and emitter was determined with the aid of the AFIWC software program 'Passive Detection (PD)'. The atmosphere propagation effects and phenomena such as trapping and ducting were taken into account using the NCCOSC software program 'Engineer's Refractive Effects Prediction System (EREPS)'. The performance of COMINT systems against representative RF receiver and transmitter systems, including cellular and SATCOM systems in the UHF band, was evaluated and summarized in a matrix, as the end product of this work. The unclassified study was limited to the capability of the modeling programs, including the availability of the environmental data concerning the area as well as the characteristics of the equipment evaluated. Geolocation was not included</dd>
