Abstract

The accurate simulation of water vapour radiometers (WVRs) prior to prototyping and laboratory testing has been a shortcoming in the state-of-the-art, despite the benefits to system development time and cost reduction. This paper presents a new approach to simulate and analyse the performance of different WVR topology designs by using a commercial RF system simulator, AWR’s Visual System Simulator (VSS). Several WVR topology designs are evaluated, using component data from vendors or state-of-the-art published literature. The results indicate good correspondence with prior measurement results, but also enables the retrieval of performance metrics (such as temperature sensitivity) previously unavailable as a simulation data product.
