First off, this is my first post here. If this is in the wrong section I apologize and ask that it be moved. I am a amateur radio operator. We have experienced issues with a rogue radio operator recently, who is maliciously transmitting noise. I think it is possible to determine his position geometrically, but its been a long time since I have done this sort of thing. To begin with Ill describe the system as much as possible. I am receiving the signal directly from the rogue transmitter, and also the signal as re-transmitted through a repeater.(At a different frequency) This means that if we describe the positions of myself, the rogue transmitter, and the repeater as a triangle, I am receiving the signal directly through a straight line, and through the other two lines as transmitted through the repeater. Therefore, there is a time gap between the two signals I am receiving. With an oscilloscope I can measure the difference in time between the two paths, and since we can assume speed of the signal to be c, I know the difference in total distance travelled. We have multiple observers who can take these measurements from as many locations as necessary, but thanks to my rusty geometry skills I am hitting a brick wall trying to solve this. I am almost 100% sure this solvable, but I am not sure I can do it. Thanks for any help you might be able to provide, let me know if my description of the situation is confusing or inadequate.
