Airborne radar altimeter return waveform computations
Radar altimeter experiments have shown the need for expanding the downward-looking, single-beam system into a multiple beam radar altimeter employing off-nadir altimetry so that information from a wider swath can be obtained from a single overflight. Problems associated with off-nadir altimetry …

Evolving subglacial water systems in East Antarctica from airborne radar sounding
… the margins of the ice sheet. This research uses airborne radar sounding, with its unique ability to infer properties within and at the base of the ice sheet over large spatial scales, to locate and characterize this unique environment. Subglacial lakes, the primary storage mechanism for …

Structure of an east coast cyclone derived from airborne radar and model diagnostics
Data from airborne W-band radar along with Weather Research and Forecasting (WRF) Model thermodynamic fields and air-parcel back trajectories from the HYSPLIT model are used to determine causes of finescale features of a northeast U.S. cyclone and link them to synoptic and air mass structure. The …

Robust Steering Vector Mismatch Techniques for Reduced Rank Adaptive Array Signal Processing
… reduced rank adaptive signal processing for airborne radar space-time adaptive processing (STAP) and steering vector mismatch robustness. This is an important area of research in the field of airborne radar signal processing since practical STAP algorithms should be robust against various …

Interaction of an upper-tropospheric jet with a squall line originating along a cold frontal boundary
… squall line, respectively, with X-band Doppler radars. Data from these two airborne radar systems have been synthesized to produce a quad-Doppler analysis of the squall line, yielding a detailed three-dimensional kinematic analysis of its structure. A simulation of the squall line was carried …

Numerical simulations of mesoscale convective systems: techniques for comparison with observations and a high resolution analysis of flow patterns in the convective region and transition zone of a simulated mcs
… for such comparisons. In Chapter 2 of this work, airborne radar observations taken during the 9-10 June 2003 MCS observed during BAMEX are compared against numerical simulations performed using the Weather Research and Forecasting (WRF) model. Comparisons are carried out using the equivalent radar …

Observed microphysical characteristics and inferred thermodynamic processes contributing to the structure, evolution, and maintenance of nocturnal elevated mesoscale convective systems
… Elevated Convection at Night (PECAN) project, airborne radar and optical array probe data were collected within 42 spiral ascents/descents of the NOAA P-3 aircraft across various regions of six mesoscale convective systems (MCSs) at multiple stages of system development. These spirals sampled …
