A Fast-Study Model of Aircraft Magnetic Field Based on Two Flights Data

摘要: In order to reduce the study time in magnetic survey, a fast-study model of aircraft field was put forward here on basis small signal proposed by S.H. Bickel. The fast uses original induced and eddy-current parameters recalculate new permanent parameters. It can flight amount from two four; so be reduced about 4 8 min at one time. Finally, simulation conducted compare compensation effects between model. result showed that effect still very close So used survey if is limited.
