摘要: Abstract Measuring the geomagnetic field accurately in real time is essential for high-precision navigation missiles. Infrared seekers contain a permanent magnet, which interferes with measurement terribly. The existing researches on modeling and shielding are generally basis of mathematic methods compensation. Here, we explore physical method to weaken magnetic improve accuracy measurement. Galerkin finite element scalar potential first introduced, distribution interferential infrared analyzed, an emphasis various schemes simulated using software ANSYS. In addition, measured values obtained via experiments accordingly. comparison values, good effects have been achieved. results guiding significance not only improving measurement, but presenting based method.
