In this paper we present a phase-space approach that models wave fields reflected from random surfaces. By using transformations based on the Wigner distribution function (WDF), we represent the diffuse wave fields in phase-space. This representation offers an efficient approach for modelling complex and noisy sources. We focus on the application of this approach to modelling of wave fields reflected from rough Earth, with potential applications in microwave remote sensing.
