Hybrid magnetic memory observation signal processing method, device and equipment

The invention provides a mixed magnetic memory observation signal processing method, device and equipment, and relates to the technical field of magnetic memory signal processing, and the mixed magnetic memory observation signal processing method comprises the steps: obtaining a mixed magnetic memory observation signal, collected by a sensor, of a ferromagnetic material; performing feature space mapping on the mixed magnetic memory observation signal to obtain mapping data; determining a separation matrix according to the mapping data; and carrying out separation processing on the mixed magnetic memory observation signal according to the separation matrix to obtain a separated target magnetic memory signal. According to the scheme provided by the invention, the source magnetic memory signal containing the defect characteristic signal of the ferromagnetic material can be effectively separated from the mixed magnetic memory observation signal, and the defect of the ferromagnetic material can be more accurately
