Magnetic turbulence detection of targets based on passive probing system

With the rapid development of target detection techniques,shortcomings of active radar in the military field become obvious and the requirements for invisible detection methods become more straightforward.A passive detection system to detect magnetic vectors for target signal detection and position is proposed.The method is based on using magnetic sensor arrays to measure background geomagnetic turbulence,and use techniques including filtering,threshold detection,basis function expansion to obtain useful signals.Then through velocity prediction,vector localization to predict the moving status of the target.Both theoretical analysis and simulation proves the method is correct,and the on-site measurement shows the method is highly applicable.
