Anomaly characteristics of magnetic field around ferromagnetic target and target azimuth analysis

Abstract

In the combat environment, the effective detection of target position is one of the important contents of precision guided munition research. Under the action of the geomagnetic field, magnetic field distortion will be generated around the ferromagnetic metal target. Based on this magnetic phenomenon, this paper models and simulates the geomagnetic field and ground targets, analyzes the characteristics of magnetic field distortion around the target, and summarizes the characteristics of the magnetic field around the target and its location The correlation law of, provides data basis for subsequent target orientation recognition. Recognizing the position of the target based on the magnetic characteristics can promote the timely adjustment of the ammunition's attitude during the flight, detonate in the best way, and maximize the concentration of firepower to damage the target.
