The hyperbolic Kepler equation (and the elliptic equation revisited)
A procedure is developed that, in two iterations, solves the hyperbolic Kepler's equation in a very efficient manner, and to an accuracy that proves to be always better than 10−20 (relative
Procedures for solving Kepler's equation
We review starting formulae and iteration processes for the solution of Kepler's equation, and give details of two complete procedures. The first has been in use for a number of years, but the second
The application of spatial filtering methods to urban feature analysis using digital image data
Abstract We describe a method of spatial filtering in the frequency domain which enhances edges and boundaries, thus making small urban features such as parks, tree-lined streets and new housing
Ground penetrating abilities of a new coherent radio wave and microwave imaging spectrometer
The early use of synthetic aperture radar (SAR) and lidar systems from aircraft and space shuttles revealed the ability of the signals to penetrate the ground surface. Atomic dielectric resonance
Invisible ADR light recognition of subsurface rocks and rock successions
When pulsed electromagnetic radio-waves pass through a material they generate measurable responses in terms of energy, frequency and phase relationships. Following early applications of Atomic
The Look-Angle Prediction Programs PLAP, ESPLAP and 6130PLAP.
Abstract : Descriptions are given of three Fortran programs for the predictions of satellite look angles: PLAP, a member of the PROP family of programs, is limited to prediction for a single station;
