Existing unexploded ordnance detection equipment based on geomagnetic anomaly and electromagnetic induction methods are usually designed as separated equipment. To improve detection probability, classify and identify ability and reduce false alarm probability, multiple equipment with different principles are required to acquire multi-sensor data for fusion processing. This proposal employs the magnetoelectric effect of magnetostrictive/piezoelectric laminate composite to design high-resolution magnetic sensors and array with the ability of static/ dynamic wideband response, and take this as the key point, to develop the new method of measuring the geomagnetic anomaly signal and electromagnetic induced eddy current signal of unexploded ordnance by single equipment. The novel design method of the magnetoelectric probe with parallel anti-phase excitation and nonlinear differential output is proposed. The intrinsic noise model and the noise transfer model of the sensing circuit are established and the noise suppression is processed. The basic models of geomagnetic magnetization and electromagnetic eddy current induction of various target as well as the magneto-electric response model of composite sensitive array under the three operating modes of geomagnetic anomaly detection, electromagnetic induction time domain /frequency domain will be established. The researches on target recognition and classification methods will also be carried out based on the analysis and extraction of the target signal characteristics and spatial characteristics of the array in the three modes as well as the strategy of multi-feature fusion. The research results based on the above principles and methods will not only reduce the weight and volume of the equipment, but also realize the ability of acquiring sensor data in multi-mode by single equipment, providing a new technical approach for the high-efficiency detection and high-precision classification of various complex targets.
