Aeromagnetic gradient direct measurement with high accuracy becomes possible with the rapid development of a superconducting quantum interference device (SQUID). The superconducting full tensor magnetic gradiometer provides a large amount of information, and high magnetic field sensitivity and other characteristics is the future direction of the new generation of airborne magnetic detection. Sensors also brought greater precision to noise suupression. How to effectively suppress aero-geophysical noise is a key technical problem. In addition to the hardware device by the method of jamming, most conventional soft compensation methods only consider the impact of traditional sources of interference measurements, but often a more complex system of noise in actual flight measurement process, only by means of a single model and associated all kinds of complex processes is difficult to adequately filter out interference. We propose a gradient magnetic data processing method of compensating a more systematic compensation to improve the effectiveness of the actual measurement data.
