The implementation of a Multi DSP radar signal processor for a Ku-Band Earth orbiting scatterometer is discussed. A testbed has been assembled using a combination of commercial DSP hardware and spaceflight components to ...

memoryless channels. First, we derive the maximum likelihood decision rule and an exact expression for the symbol error rate for n ≥ 1, avoiding a numerically unstable aspect of the n = 1 formula of [GK76] and generalizing ...

An application for registering and merging multiresolution terrain models is presented and some of the associated tools are discussed.

The heat tranfer process that results from gaseous diffusion through the nucleus is shown to play a significant role in modeling comet nulei. In this paper, a comprehensive comet nucleus model is presented which simulates ...

A primary goal of the astrobiology program is the search for fossil records. The astrobiology exploration strategy calls for the location and return of samples indicative of environments conducive to life, and that best ...

Well calibrated, high resolution multiband thermal infrared (TIR) images of the Earth's surface can

The Cassini Spacecraft will soon journey to Saturn to perform a close-up study of the Saturnian system; its rings, moons, magneto-sphere, andf the planet itelf. Sequences of commands will be sent to the spacecraft by ground ...
