A Method and System For Optimizing The Efficiency of SIGINT Collection Systems on Mobile Platforms with Limited Bandwidth Connections that is implementable in legacy signal collection systems. The resultant system first reduces potential upload bandwidth by eliminating whitespace in collected signals. Next, the system ignores collectable signals based on signals frequency or angle of arrival so as to identify energy of interest. Next, the system score and attributes a priority to each energy of interest, now known as signals of interest. The system then increases collection bandwidth on all signals of interest based on the score, priority and availability of resources. Finally, in real time, and based on SOI score and priority and the availability of downlink resources, the collected signal data is downlinked to the SIGINTcontrol center.
