Abstract:

The objective of this effort was to investigate Interference Cancellation System ICS techniques to solve the harmonic and intermoduation products IMP generated as the result of high power jammers, HFVHFUHF transmitter signals impinging on a nonlinear junction somewhere on the aircraft during flight. The problem becomes very complex when trying to receive a desired satellite starved signal. Since a reference sample of the nonlinear signal is not available, it has to be synthesized to a high degree of accuracy in order to be able to cancel the interfering signal. The crux of this problem is the synthesization of the nonlinear signal without concurrently cancelling the desired signal. Author
