Time-Varying Ocean-Like Surface Scattering at Grazing Incidence: Numerical Analysis of Doppler Spectrum at HF/VHF/UHF Bands

Figure 9

Numerical simulated Doppler spectrum of linear waves over operating frequency. The horizontal axis is the Doppler angular frequency normalized by the Bragg frequency, and the vertical axis represents different simulation operating frequencies from 5 MHz to 400 MHz.
