[edit] Workings

Just reading the page for info on MADs, came across the line:
"The detection range is normally related to the distance between the sensor and the submarine."
This line seems confusing, perhaps because the fact it is expressing is trivial or not clearly stated. I propose as a clarification "The detection range is the maximum distance from the sensor at which a submarine can be detected." But if this is so, it seems like it could be removed entirely because it's pretty much a true statement of any detection device. I would do it, but the meaning is uncertain enough that I'd rather leave it to someone with greater understanding of the subject. 136.242.153.127 22:52, 13 November 2007 (UTC)

Added a simple explination of the workings of a Caesium Vapour model, any corrections?? The number of energy states should be regarded as suspect, I can't recall off the top of my head.

I work with magnetometers on a regular basis for the purpose of geophysical surveys. In addition to registering a response to ferromagnetic sources, they also register dc currents quite well. I would think that in the case of submarine detection, the dc currents from the electronics and motors would register much stronger than any temperature induced potential. I can't say for sure though as we do not use them for this purpose. 63.250.178.163 18:32, 22 January 2007 (UTC)

I operated the ASQ-8 and ASQ-10 MAD apparatus in P-2s and P-3s. A submarine is an electrical conductor, and if moving through the Earth's lines of flux will have a significant induced current, although counter measures can be employed. The ASQ-81 was sensitive enough to detect the eddy currents in sea surface waves, requiring another sub-system to cancel the noise. 17:48, 30 September 2007 (UTC)
