ABSTRACT:
The system includes a transmitter, at least one detection system receiver, a modulated signal source, and a directional receive antenna. The transmitter emits a high power illuminating signal at a receive frequency of a target RF receiver to be detected. The high power illuminating signal is sufficient to cause the target RF receiver to generate harmonic emissions. At least one detection system receiver is used for detecting at least one harmonic frequency emitted by the target RF receiver. The modulated signal source is operatively associated with the transmitter to modulate the illuminating signal and for use as a reference to the detection system receiver such that the turn around time of the harmonic frequency emitted by the target RF receiver can be measured. A directional receive antenna is operatively associated with the detection system receiver for determining the angle to the target RF receiver.
