The effectiveness of magnetic sweep equipment is influenced by the water depth and the conductivity of the water (salinity and temperature).. Magnetic storms cause momentary fluctuations in the earths magnetic field. These storms sometimes closely resemble the magnetic signature of a ship and may result in magnetic influences firing mines prematurely. ACOUSTIC ENVIRONMENT Ambient noise can create problems for mines and MCMs in shallow water.. High ambient noise levels present a problem for the performance of acoustic influence mines, since the target must be discriminated from ambient noise over relatively long ranges.. High-frequency components of ambient noise tend to have little effect on minehunting operations because of the high receiver directivity characteristics of minehunting sonar systems.PRESSURE ENVIRONMENT Water pressure can play a significant role in MIW operations.. The effective pressure change caused by wave heights at the surface diminishes with increasing depth.. Generally, pressure mines require other influences, such as acoustic or magnetic influences to be present simultaneously in order for the mine to explode.This information is now available on CD in Adobe PDF Printable Format |
