We develop and then demonstrate a modified planar subarray processing algorithm based on the inverse scaled Fourier transform applied to very high frequency ice-sounding data that produces swath measurements of ice sheet surface topography, ice thickness, and radar reflectivity of both internal reflecting horizons and bedrock of the ice sheet. It is a real-time ice-sounding imaging method. First,...
In this paper, we propose an approach to integrate the radio-frequency interference (RFI) mitigation technique into a real-time synthetic aperture radar (SAR) imaging algorithm applied to very high frequency (VHF) ice-sounding data that produces swath measurements of ice sheet surface topography, ice thickness, and radar reflectivity of both Internal Reflecting Horizons (IRHs) and bedrock of the ice...
Scene management is one of the key technologies in virtual reality systems, particularly for those based on Web3D. Taking into account the characteristics of underground (UG) scene, a lightweight scene management mechanism for real-time visualization of large-scale scene over the internet is proposed. Firstly, a lightweight preprocess method is employed to simplify the raw data with which the whole...
