A new automated observatory dedicated to the radiometry of the moon has been constructed to provide new radiance information for calibration of earth-orbiting imaging instruments, particularly Earth Observing System instruments. Instrumentation inclu

The project to develop a line-integral approach to 2-dimensional radarclinometry and to bring it to the status of producing topographic maps from real radar images has been concluded. The final developments of the theory itself have involved a trial-

The December 13, 1995, Eos “In Brief” column refers to the “new” establishment of knowledge of the geometrical dependence of the Moon's diffuse reflectivity for phase angles under 1.5°, normally inaccessible to Earth-based observation becaus

Astronomers routinely violate the directive to sample surface brightness with at least twice the frequency of the highest spatial frequency of the Fourier transform of the continuous image, when doing direct CCD imaging. It is reasonably speculated t

A widely deployed experiment in freshman physics tests the hypothesis that the magnitude of the central force that accomplishes uniform circular motion is mv2/r (equivalently mrω2). This is accomplished by using a spring rotating about one end as th

A method for determining the dependence of radar backscatter on incidence angle that is applicable to the region corresponding to a particular radar image is derived. The method is based on enforcing mathematical consistency between the frequency dis

The understanding of quantum mechanical phenomena has come to rely heavily on theory framed in terms of operators and their eigenvalue equations. This paper investigates the utility of that technique as related to the reciprocity principle in diffuse

The question of adapting to radar images the existing hardware that form topographic maps through stereo-photogrammetric models, is examined in principle. Such hardware utilizes a human/ computer hybrid. Although the problem of brightness differentia

Because radarclinometry is fundamentally describable in terms of a nonlinear, first-order, partial differential equation, one expects that it can, in principle, be carried out by direct deterministic integration beginning at a given threshold profile

Advances over previous work in radarclinometry (Wildey, 1984 and 1986) are proposed, including incorporation of a more exact treatment of the dependence on terrain orientation of the solid angle of integration of the microwave specific energy compris
