Abstract :
The probability model of multipath delays is proposed for scattering centres above the ocean surface. The surface is endowed with the Kirchhoff approximation, as well as a probability density function of the elevations and slopes. The model faithfully reflects the stochastic character of the multipath delays in imaging radar echoes. Moreover, it explores a way to simulate the synthetic aperture radar images without the time-consuming process of electromagnetic computation.
