In order to realize wide range detection

accurate identification

precise positioning on cruise missiles

a system for cruise missiles recognition and positioning based on magnetic field disturbance detection is proposed.According to the law of Biot-Sand the Laval law and electromagnetic induction

design a method for inversion feature information of cruise missile such as position and distance by magnetic field disturbances

and establish corresponding mathematical model.Through simulation analysis

the intensity of magnetic field perturbation depends primarily on distances between the measured object and the magnetic detector

size and velocity of the measured object.By Matlab simulation

the function relationship diagram of intensity of the magnetic field disturbance and three parameters is given.Experiment adopts metal column analog proportionally physical process that cruise missiles flying through constant magnetic field

get intensity of magnetic field turbulence under different conditions of different distance

different speed generated from measured metal column

inverses the characteristic information of the measured object.Experiments show that the principle is feasible

detection range and precision can be adjusted according to specific requirements.
