CReSIS airborne radars and platforms for ice and snow sounding

Autor: Fernando Rodriguez-Morales, John Paden, Emily Arnold, Shawn Keshmiri, Carl Leuschen, Jilu Li, Richard D. Hale

Publikováno v: Annals of Glaciology. 61:58-67

This paper provides an update and overview of the Center for Remote Sensing of Ice Sheets (CReSIS) radars and platforms, including representative results from these systems. CReSIS radar systems operate over a frequency range of 14–38 GHz. Each rad

Radar Systems for Ice and Snow Measurements Onboard Manned and Unmanned Aircraft

Autor: John Paden, Shawn Keshmiri, Daniel Gomez-Garcia Alvestegui, Richard D. Hale, Fernando Rodriguez-Morales, Carlton J. Leuschen, Carlos Cárdenas, Emily Arnold, Jilu Li

Publikováno v: IEEE Latin America Transactions. 16:2473-2480

In this paper, we present a brief overview of the state of the art in radar systems for ice and snow measurements. Emphasis is given to the instrumentation developed at the University of Kansas for multi-band data retrieval at frequencies ranging fro

Airborne Measurements of Snow Thickness: Using ultrawide-band frequency-modulated-continuous-wave radars

Autor: S. Gogineni, Carlton J. Leuschen, D. Gomez-Garcia, Sinead L. Farrell, Fernando Rodriguez-Morales, John Brozena, Jacqueline A. Richter-Menge, John Paden, Jilu Li, Jie-Bang Yan, Richard D. Hale, David Braaten

Publikováno v: IEEE Geoscience and Remote Sensing Magazine. 5:57-76

Frequency-modulated-continuous-wave (FM-CW) radar has been used extensively for the airborne measurement of snow thickness over sea ice and the mapping of annual accumulation over land ice. In contrast to conventional in situ measurements, FM-CW rada

Nonlinear aerodynamics of an unmanned aircraft in wind shear

Autor: Edward Lan, Richard D. Hale, Shawn Keshmiri

Publikováno v: Aircraft Engineering and Aerospace Technology. 89:39-51

Purpose The purpose of this paper is to evaluate the accuracy of linear and quasi-steady aerodynamic models of aircraft aerodynamic models when a small unmanned aerial system flies in the presence of strong wind and gust at a high angle of attack and

Multichannel Wideband Synthetic Aperture Radar for Ice Sheet Remote Sensing: Development and the First Deployment in Antarctica

Autor: Fernando Rodriguez-Morales, Carlton J. Leuschen, Robby Willer, D. Gomez-Garcia, S. F. Child, Bryan Townley, John Paden, Calen Carabajal, Leigh A. Stearns, Richard D. Hale, Sivaprasad Gogineni, Jilu Li, Z. Wang, David Braaten, Jie-Bang Yan

Publikováno v: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing. 9:980-993

We developed a multichannel wideband synthetic aperture radar (SAR) that operates over a frequency range of 190–450 MHz for measurements over the ice sheets in Antarctica and Greenland. The antenna-array, which consists of eight elements housed in
