Welcome to War and Tactics!    War and Tactics Forum is currently undergoing some modifications that might disable features you are used to. This is unabvoidable as we have to update the forum engine to a new structure that is incompatible with many of the features we had used so far. The good news: WaT will be more secure and stable, and most of the features we uninstalled will be a natural part of the new structure anyway. For the rest we will be looking for solutions.

According to Wikipedia, Gravity Gradiometry is the study and measurement of variations in the acceleration  due to gravity.

Lockheed has been awarded a contract to develop a sensor that uses this method to map tunnels and other subterranean structures, in order to provide data for attacks, as they published in a press release:

Quote
The Defense Advanced Research Projects Agency (DARPA) awarded Lockheed Martina $4.8 million contract to design a sensor system that can locate and identify underground targets by spotting gravity-based effects from an airborne platform.

Under DARPA’s Gravity Anomaly for Tunnel Exposure (GATE) program, Lockheed Martin will develop a prototype sensor and system that can detect, classify, and characterize subterranean threats such as tunnels, bunkers, and caches. The sensor system incorporates a gravity gradiometer, an instrument which measures the tiny variations in the pull of gravity. The GATE sensor will detect those variations to discriminate a man-made void from naturally-occurring features such as topography and geology, yielding a near real-time map of what is underground. -snip-
