Multiple Access Low Probability of Intercept Networks
Abstract
Increased demands for communications in the tactical battlefield have fueled the development of multiple access Low Probability of Intercept networks. Most detectability studies of LPI networks have focused on the individual links of the network, in which the intercept and detectability calculations are conducted for a single network transmitter. The research reported here examines a different approach to network detectability analysis: It is assumed that the interceptor does not attempt to distinguish one emitter from another, but rather decides only if a network is operating or not. what distinguishes this approach from conventional link intercept analysis is that detection decisions are based on energy received from multiple sources. Two network detection models are developed. A dispersed network intercept model is appropriate for scenarios in which the network transmitters are dispersed throughout a given tactical region, and the interceptor is inside the network. The interception area for the specified probabilities of detection and false alarm is used as a performance metric. A stand-off network intercept model is used for situations in which the network transmitters are collocated and the interceptor is standing off. For this model, a network LPI quality factor is developed as a performance metric. Both models are developed for a frequency hopping code division multiple access network, using a wideband radiometer and filter band binary moving window detector as potential intercept receivers.
