System and Method for Allocating Jamming Energy Based on Three-Dimensional Geolocation of Emitters
First Claim
1. A system for locating an emitter and transmitting jamming signals at said emitter within an area comprising:
- a receiver to receive signals transmitted by said emitter and obtain measurements of said received signals at a plurality of different locations within said area;
a processor to process said measurements to locate said emitter within said area, wherein said processor includes;
a location module to process said measurements and determine a three-dimensional location of said emitter within said area based on relationships of distances between said emitter and each of said plurality of locations, wherein said measurements are proportional to said distances; and
a transmitter to transmit said jamming signals at said emitter based on said three-dimensional location of said emitter within said area.

Abstract
According to an embodiment of the present invention jamming energy is allocated to a plurality of emitters based on a three-dimensional (3-D) emitter geolocation technique that determines the geolocation of radio frequency (RF) emitters based on energy or received signal strength (RSS) and/or time differences of arrival (TDOAs) of transmitted signals. The three-dimensional (3-D) emitter geolocations are used to rank emitters of interest according to distance and available radio frequency (RF) jamming energy is allocated to the emitters in rank order. The techniques may be employed with small unmanned air vehicles (UAV), and obtains efficient use of jamming energy when applied to radio frequency (RF) emitters of interest.
