In this paper, we discuss the progress being made on the design and construction of the single-stage, two-channel Kaband thermal compensating receiver for the Surface Water and Ocean Topography mission (SWOT). The fundamental signature utilized by SWOT for performing topographic measurements of the ocean and surface water is that of the interferometric phase between two channels in the receiver. While the frequency of 35 GHz has the advantage of a compact spacecraft structure and allowing a… Expand

TLDR
A new digital circuit is developed which can detect minute phase differences in time-varying analog signals which allows for the real-time monitoring of environmental metrics, such as temperature fluctuations, which affect signal phase. Expand
Real-time estimates of differential signal phase for spaceborne systems using FPGAs
TLDR
A new, adaptive phase difference detection circuit that can be implemented in reconfigurable hardware is described and can be used for anomaly detection for a variety of spaceborne applications, eliminating the need to transmit data for further terrestrial processing. Expand
