Radar Emulator

Thus far the bulk of my research has focused on a software radar emulator/simulator which is described in May et al. 2007. The initial application focused on testing how tornadic signatures in radar data degraded as a function of range and sampling intervals for a broad beam radar. An example of the simulated data is shown below.

Current work on the emulator includes adding full time-series simulation as well as an upgrade on the scattering model from the Rayleigh assumption to a full scattering calculation that allows for non-spherical particles as well as resonance effects. Currently, T-matrix and Discrete Dipole Approximation methods are being evaluated.
