Lidar sensing has been found to be a useful method of monitoring the dynamics and mass balance of glaciers, ice caps, and ice sheets. However, it is also known that ice surfaces can have complex 3-dimensional structure, which can challenge their accurate retrieval with lidar sensing. In support of future lidar sensing satellite missions, such as the(More)
Simulation of synthetic aperture radar (SAR) imagery may be approached in many different ways. One method treats a scene as a radar cross section (RCS) map and simply evaluates the radar equation, convolved with a system impulse response to generate simulated SAR imagery. Another approach treats a scene as a series of primitive geometric shapes, for which a(More)

To advance the science of lidar sensing of complex ice and snow surfaces as well as in support of the upcoming ICESat2 mission, this paper establishes a framework to theoretically study a spaceborne micropulselidar returns from snow and ice surfaces. First, the anticipated lidar return characteristics for a sloped non-penetrating surface is studied when(More)
This poster addresses the so-called boundary bias associated with Photon Mapping [Jensen 2001] as well as bias resulting from sparsely populated spectral maps. This work is done in the context of modelling spectrally and spatially variant coastal waters for remote sensing applications. We are particularly interested in simulating hyperspectral scenarios(More)
Sensor reaching radiance in coastal ocean-water environments contains contributions from the air-water interface, in-water objects, and the participating volume itself. If rendered by a forward-modeling synthetic image generation program, the imagery must account for several interesting phenomenon, including, but not limited to; volumetric scattering,(More)
