Statistical Analysis of Radar Rainfall Error Propagation

The prediction uncertainty of a hydrologic model is closely related to model formulation and the uncertainties in model parameters and inputs. Currently, the foremost challenges concern not only whether hydrologic model outputs match observations, but also whether or not model predictions are meaningful and useful in the contexts of land use and climate change. The latter is difficult to determ...

Measuring Vertical Rainfall Velocity through Spaceborne Doppler Radar: Performance Analysis and System Requirements

In this paper we will present the results of the trade studies on the performances of a spacebome Doppler radar in measuring vertical rainfall velocity. Particular emphases will be placed on: 1) the choice of the PRF vs. antenna size ratio, 2) the choice of the observational strategy, 3) the choice of the operating frequency; and the 4) processing strategy. The results show that accuracies of 1...

Doppler Radar Tracking Using Moments

A Doppler radar is a specialized radar that makes use of the Doppler effect to estimate targets velocity. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object’s motion. This variation gives direct and highly accurate measurements of the radial component of a ta...

Improved Micro Rain Radar Rainfall Measurements using Doppler Spectra Post-Processing

The Micro Rain Radar 2 (MRR) is a cost effective, minimum maintenance oriented, portable radar system used for conducting precipitation research. This system is prone to several draw backs such as lack of a sophisticated post-processing algorithm to improve its sensitivity, noise due to radar receiver and the lack of high quality Doppler radar moments. In this project work, we propose an improv...
