Abstract

A system which detects the presence and bearing of a mass M implemented by having a first field or wave interact with the motion of a charged mass m to produce a second field or wave which is modulated by the tidal effect of mass M. The second field or wave with unique tidal signal is then detected. The system can be implemented as a magnetic resonance spectrometer, gyrotron, cyclotron, Fourier Transform-Mass Spectrometer (FT-MS), or even as a large spinning mass and permits the substantial increase in the sensitivity of practical gravitational mass detectors and gradiometers and thereby permitting the detection of earthbound objects such as ore deposits, ships, submarines, tanks, artillery, and small concealed handguns and may extend gravitational mass detection capabilities to space and galactic objects.
