During the PEAK (Propagation Effects Assessment - Kwajalein) experiment in August 1988, The ALTAIR VHF/UHF wide bandwidth radar was used to track spherical satellite in low-earth orbit. The purpose of the experiment was to obtain radar data during the most severe propagation disturbances available naturally. The PEAK experiment has been quite successful, giving many measurements of strong scintillation as well as the first measurements of frequency-selective fading on propagating radar pulses....

This thesis describes the study and development of a workable inverse scattering method for imaging and identification of radar targets. The space-time integral approach is used for iterative target shape reconstruction. Following an overview of transient electromagnetics, the integral equation is applied for thin-wire transient response computation. The analytical time domain integral equation is derived and solved numerically, for general conducting bodies of revolution. Finally the algorithm...

The position of the earth's spin axis with respect to the crust (polar motion), was computed for the last three months of 1980 by the Defense Mapping Agency Aerospace Center on the basis of Doppler observations of the GEOS-3 satellite. The results were obtained as a contribution to project MERIT, an international compaign to determine the best technique to replace classical astronomical procedures used to determine polar motion since 1900.
