[mag′ned·ik ə′näm·ə·lē di‚tek·tər]
(electromagnetism)
A sensitive magnetometer carried at the end of a boom projecting from the tail of a patrol plane which can detect very small changes in the earth's magnetic field caused by a ferrous object, such as a submerged submarine; used to pinpoint a submarine's location, for effective deployment of suitable weapons. Abbreviated MAD.

magnetic anomaly detector (MAD)

A sensitive magnetometer that can detect very small changes in the earth's magnetic field caused by a ferrous object, such as a submerged submarine. It is carried at the end of a boom projecting from the tail of a plane and used to pinpoint a submerged submarine or magnetic deposits in the earth.

Therefore, the vehicular magnetic anomaly detection requires high-resolution sensors and alternative signal processing algorithms to extract desired traffic flow information.
Originally known as the VP-17 "Blind Foxes," hinting at the ability to fly blindly into adverse weather conditions, the squadron became VP-5 in 1948 and renamed "Mad Foxes" for the Magnetic Anomaly Detection (MAD)-equipped P2V Neptune that could detect large objects underwater.
CAE also delivers a range of operational ISR solutions to Canada and the global market, including magnetic anomaly detection for anti-submarine warfare, electronic warfare suites for land forces, and augmented visionics solutions for aircraft navigation in degraded visual environments.
Officials said the government is expecting delivery next year of three new Augusta-Westland AW 109 helicopters equipped with submarine-hunting hardware such as sonar and magnetic anomaly detection (MAD) device and search and rescue hardware.
Stress levels within magnetic anomalies less than 30% of SMYS will lower the probability of magnetic anomaly detection (hereinafter referred to as POD) below 80% but never less than 60% (see chart in Figure 4).

Eight chapters cover the following topics: SQUID voltmeters and amplifiers, the magnetic inverse problem, biomagnetism, measurements of magnetism and magnetic properties of matter, nondestructive evaluation of materials and structures using SQUIDs, gravity and motion sensors, and SQUIDs for standards and metrology and geophysical survey and magnetic anomaly detection. Along with those specializing in SQUID technologies, this book may be of use to advanced students and professionals in physics, astrophysics, cosmology, chemistry, materials science, standards, biology, and medicine.
