Abstract
A method of estimating a location of an interference signal source includes using a first antenna configured to receive a signal from the interference signal source and using a second antenna arranged proximate to the first antenna and configured to receive global positioning system (GPS) signals. An initial trend in variation in power of a received signal from the interference signal source is determined relative to a position of the second antenna, wherein upon determining the initial trend, the initial trend is a current trend. In an iterative manner, the second antenna is directed to be repositioned. A secondary area associated with a lack of power measurement outside of an area traveled is identified and a further repositioning of the second antenna is determined to reduce the secondary area. An estimate of the location of the interference signal source is then determined.
