Interference Emitter Localization Based on Hyperbolic Passive Location in Spectrum Monitoring
Interference signals can always be found during spectrum monitoring, which has a serious impact in the regular use of radio business . Sometimes is difficult to shied it by suppress signal, so it is becoming increasingly important to find the location of the interference emitter . This paper proposed an effective technique in interference emitter localization based on intersections of hyperbolic curves defined by the time differences of arrival of a signal received at three monitoring stations. The approach is noniterative and gives an explicit solution. In the end, this paper token a field test based on the hardware platform, the final result is given.
