This buried security system is based on the Magnetic Anomaly Detection principle of operation.

Magnetic anomaly detection (MAD) equipment was sometimes housed in a tail boom.

Did Aaron say anything about finding it with Magnetic Anomaly Detection?"

Reading sonargrams, magnetic anomaly detection equipment, physics, wave propagation, oceanography, meteorology.

If the air unit has magnetic anomaly detection (MAD) as well as sonobuoys then so much the better.

Magnetic anomaly detection (MAD)

Magnetic Anomaly Detection (MAD) is used in antisubmarine water, for final localization before attack.

MAD: Magnetic Anomaly Detection.

They even got positive MAD (magnetic anomaly detection) contact, but they lost contact after tracking the submarine for about twenty minutes.

For the application of magnetic anomaly detection, sensors at different spots have to be used to cancel the spatial-correlated noise in order to achieve a better spatial resolution.

The anti-submarine variant has a large air-to-surface search radar, a side-looking ISAR radar and a magnetic anomaly detection tube.

This signature can be exploited by magnetic mines, or facilitate the detection of a submarine by ships or aircraft with magnetic anomaly detection (MAD) equipment.

Their mission was to locate and destroy German U-boats in the relatively shallow waters around the Strait of Gibraltar where magnetic anomaly detection (MAD) was viable.

"Sir, if you won't allow a weapon release for the north task force, we at least need to verify these contacts in the Bohai Haixia with our helicopters, the units with magnetic anomaly detection."

In mid-2008, the Naval Air Systems Command (NAVAIR) deleted the requirement for the P-8A to be equipped with magnetic anomaly detection (MAD) equipment.

Magnetic Anomaly Detection gear measured the background magnetic fields of the earth and re-corded the changes in the fields that occurred when a large chunk of iron passed between the detector and the earth.

During the Vietnam War the original AC-130 gunship gunships employed the "Pave Mace"/"Black Crow" magnetic anomaly detection system to detect truck ignition coils in vehicles hidden under heavy jungle canopies.

In addition to resetting their depth charges to deeper depths, Japanese anti-submarine forces also began employing auto-gyro aircraft and MAD (magnetic anomaly detection) equipment to sink U.S. subs, particularly those plying major shipping channels or operating near the home islands.

These six blimps initially conducted nighttime anti-submarine warfare operations to complement the daytime missions flown by FAW-15 aircraft (PBYs and B-24s) using magnetic anomaly detection to locate U-boats in the relatively shallow waters around the Straits of Gibraltar.
