So accurate phase noise simulation is of great importance during the design and development of bistatic SAR systems. This letter concentrates on the impacts of limited oscillator stability between bistatic transmitter and receiver, and presents an analytical model of phase noise that solves some drawbacks implicitly present in the previously proposed models. This model uses the Gaussian noise as the input of a hypothetical low-pass filter and its output is then considered as phase noise. Finally, some simulation results are provided to demonstrate the validity of this model. 收起
