Comparison of Aircraft Maneuver Compensators for Antisubmarine Warfare Magnetometers.

摘要

Submarines can be detected from the perturbations they cause in the earth's magnetic field. Aircraft mounted magnetometers are used to detect these perturbations. Magnetic compensators are used to minimize the aircraft's effect upon the magnetometer signal. The Naval Air Development Center has compared the performance of two advanced magnetic compensators, the Integrated Digital Magnetometer (IDM), and the Compensator Group Adaptor (CGA), developed for ASW aircraft. Data for the comparison were collected on 21 test flights during the latter half of CY 1980. All test objectives were met. The compensation quality (as measured by Figure of Merit) of both systems was well within the level considered acceptable by the fleet. Residual maneuver noise left by the IDM was approximately 30% less than that of the CGA. There was no significant difference in required compensation time. A cost effectiveness analysis is recommended.
