Self-adaptive magnetic anomaly target imaging and detection method

The invention discloses a self-adaptive magnetic anomaly target imaging and detection method. According to the method, a magnetic anomaly target signal is expressed by adopting three self-adaptive primary functions, so that the moving path of a measuring platform can be any and is not limited to uniform linear motion, and the target signal can also be detected at the turning of a measuring line; the invention provides a method adopting a self-adaptive detector, a model coefficient is solved integrally, and a platform interference magnetic field, a geomagnetic gradient field, a daily variation magnetic field and an abnormal magnetic target signal are separated; according to the magnetic anomaly target imaging method provided by the invention, the pixel value is the ratio of signal energy to data segment energy and reflects the probability that a target exists at an imaging position; finally, the invention provides a method for detecting whether the target exists along the measuring line direction, also provide
