SATELLITE SENSOR DETECTION OF A MAJOR METEOR EVENT IN THE UNITED STATES ON 27 MARCH 2003: THE PARK FOREST, ILLINOIS BOLIDE
- Environmental Science
- 2004
A major meteor explosion in Earth’s atmosphere occurred over Park Forest, Illinois on 27 March 2003 at 05:50 UT (11:50 PM local time). The event resulted in a large-scale meteorite fall over the…
A proposed multidimensional analysis function
- GeologySPIE Defense + Commercial Sensing
- 2003
Previous work has suggested a potential value in the combination of physical property data types (e.g. magnetic and terrain slope) when searching for oil and mineral deposits. This work studies a…
Determining Probability Upper Bounds for NEO Close Approaches
- Computer Science
- 2004
This paper shows how to calculate the upper bounds of probability by determining the worst possible covariance parameters and orientation and can be used as a simple pre-filter or to determine worstcase scenarios when the actual covariances are not known.
NEO ORBIT UNCERTAINTIES AND THEIR EFFECT ON RISK ASSESSMENT
- Physics
- 2004
Threat assessment of approaching Near Earth Objects (NEOs) is best based upon the probability of collision since it yields a more accurate measure of risk than simple miss distance. The probability…
COMET, ASTEROID, NEO DEFLECTION EXPERIMENT (CANDE): AN EVOLVED MISSION CONCEPT
- Physics
- 2004
We propose a space mission to a small asteroid (1 - 2 km) that would carry a soph isticated remote sensing package and detonate a 10 MT nuclear bomb on or near the surface of the body. The goal is to…
Infrared sensor modeling for improved system design
- Computer ScienceDefense, Security, and Sensing
- 1996
This paper shows how the modeling of systems can be used to provide feedback to the design stage through tradeoff analyses, and how scanning systems can improve their performance by oversampling, but pay a penalty in higher data rates and potentially noisier output if the integration time must be lowered.
Zernike polynomials and aberration balancing
- Physics, MathematicsSPIE Optics + Photonics
- 2003
For small aberrations, the Strehl ratio of an imaging system depends on the aberration variance. If the aberration function is expanded in terms of a complete set of polynomials that are orthogonal…
CONCEPTUAL DESIGN OF AN ASTEROID INTERCE PTOR FOR A NUCLEAR DEFLECTION M ISSION
- Engineering
- 2004
A conceptual design was developed for an asteroid interceptor vehicle using a nuclear explosive to deflect Athos, a 200 -m diameter threat object. A notional concept of operations is proposed for…
Single-event effects test results of 512MB SDRAMs
- Engineering2003 IEEE Radiation Effects Data Workshop
- 2003
Single-event effect test results of new 512MB SDRAMs are reported in this paper. Effects characterized during testing include single-event upset, single-event latchup, and single-event functional…
