A Method and System for Collecting and Surveying Radio Communications From
a Specific Protected Area of Operations in or Around a Compound. It is an
object of the present invention to provide just such a method to
automatically detect communications signals in near real time, from any
selectable sub-area of a compound. Such a system would greatly enhance
the operational capabilities of the twenty-first century organization by
providing a real-time capability to secure radio communications in and
around a compound. The system has all the abilities of the system
described in the '976 application, but is further able to automatically
detect the direction of the incoming signals (relative to two or more
collector subsystems in communication with each other), and thereafter to
add that information to the surveillance decision logic such that the
actual geographical location, as adjusted by the calibration information
for the particular compound surveillance decision logic. Secondly, the
system has the capability of being calibrated such that the particular RF
environment of the compound in question is uniquely mapped. The
calibration tables maintained by each network-attached directional
collection node of the system invention in order to provide a more robust
and accurate signal geo-location system. Thirdly, the system is able to
automatically pinpoint the geographic area of the source of the incoming
signals and add that information to the monitoring decision logic.
Finally, the system provides a user interface to operators so they can
easily select areas to monitor, and easily calibrate the system for
maximum precision.
