Modern electronic warfare systems are directed against an ever increasing variety of electronic systems. It is necessary to intercept certain signals so that countermeasures or analysis can be accomplished. To accomplish the intercept, receiving systems with as high a probability of intercept as possible are required. This study examines factors causing probability of intercept to decrease and the methods that may be used to combat those factors. Receiving systems having unity probability of intercept are examined. Systems examined are the IFM, acoustooptic and two-tuple type receiver. The effects of external and internal noise, receiver and antenna scan factors, signal density, signal processors, display systems and bandwidth are factors limiting probability of intercept that are examined. One concludes that through proper design, systems can be achieved with unity intercept probability.
