Modeling and Simulation of Radio Frequency Interference for High-Frequency OTH Radar
This paper proposes to model and simulate the radio frequency interference (RFI), especially the narrowband RFI and the wideband RFI, for the high-frequency over-the-horizon (OTH) radar. Based on the theories of random process and linear filtering, the proposed models uses the white Gaussian noise as the input of a linear filter, so that the output is a random process with small bandwidth. In the filter design, seven kinds of response functions are proposed for the convolution method, and four sets of coefficients are proposed for the auto-regressive and moving-average method. Besides, extended approaches are also provided to increase the diversity of the RFI simulation. Numerical experiments demonstrate that the proposed methods can simulate most range-Doppler maps of real RFI.
