This paper addresses how the various different parameters of the bistatic return from navigation and communication Signals of Opportunity (SoOp) should be considered in bistatic modeling. The coherent and incoherent bistatic returns from Earth's surface are discussed. Furthermore, formulation for modeling ocean surfaces is reviewed for a broad range of SoOp frequencies, and different parameters for...
This paper presents results from recent satellite Global Navigation Satellite System-Reflectometry (GNSS-R) experiments in the northern high latitudes. Seasonal changes in the reflected signal are attributed to changes in the freeze/thaw state of the landscape. Here, we describe the unique geometries and sampling strategies that GNSS-R provide, which come with both advantages and limitations vis-à-vis...
