摘要: Abstract Aeromagnetic interference could not be compensated effectively if the precision of parameters which are solved by aircraft magnetic field model is low. In order to improve compensation effect under this condition, a method based on small signal and least mean square (LMS) algorithm proposed. According method, initial values adaptive filter’s weight vector calculated with through at first, then amount direction cosine its derivative set as input filter, expected vector. After that, LMS algorithm. Finally, verified simulation experiment. The result shows that can improved obviously when original have low precision. further even high
