Adaptive Jamming Method for UAV Communication Links Based on Time Modulated Technique

In this paper, an adaptive jamming method for UAV communication links with time modulated technology is proposed. By performing real-time time modulation on the received UAV communication signals, the baseband signal will be overlapped by the signals on multiple neighboring harmonics, which in turn adaptively generates the jamming signal. The spectrum expression of the jamming signal is derived by taking the 1bit phase-shift circuit for periodic modulation as an example. Simulation results and field tests verify the effectiveness of the method.
