Time-Varying Jamming Modeling and Classification

In this correspondence, we provide a general jamming model, through which all the existing models can be summarized and extended to the time-varying case under one unified framework. We analyze the time varying jamming power spectral density, and propose a new jamming classification scheme by introducing the concepts of time-varying jamming coherence time and time-frequency jamming coherence bandwidth. Specific methods on power spectrum estimation are provided for time-varying jamming that is stationary or locally stationary.
