The increasing diffusion of spaceborne GNSS reflectometry as a remote sensing technique has motivated, recently, the development of end-to-end delay-Doppler map simulators. We present here the most relevant issues involved in the design of a simulator for applications of ocean wind remote sensing with a conventional acquisition technique. The approach is based on the stochastic Monte Carlo simulation of the scattered signal followed by a 2-D convolution and filtering accounting for the Doppler processing implemented on the TechDemoSat-1 platform. Simulation accuracy is assessed in the validation setup, where ensemble runs are supported by the estimation of the empirical cumulative distribution function.

Abstract

The increasing diffusion of spaceborne GNSS reflectometry as a remote sensing technique has motivated, recently, the development of end-to-end delay-Doppler map simulators. We present here the most relevant issues involved in the design of a simulator for applications of ocean wind remote sensing with a conventional acquisition technique. The approach is based on the stochastic Monte Carlo simulation of the scattered signal followed by a 2-D convolution and filtering accounting for the Doppler processing implemented on the TechDemoSat-1 platform. Simulation accuracy is assessed in the validation setup, where ensemble runs are supported by the estimation of the empirical cumulative distribution function.
