Abstract:

Submarines can shoot magnetic decoys to resist airborne magnetic detection, aiming at the evaluation of magnetic decoy’s antagonism effectiveness, firstly, the application characteristics of the magnetic field curve similarity measurement method in the magnetic field similarity measurement method based on discrete Fréchet distance are analyzed. Combined with the characteristics of the motion trajectory when the anti-submarine aircraft meets the decoy, a decoy magnetic field effectiveness evaluation method based on detection probability is proposed, and the description of the confrontation probability under typical demand scenarios is given, and the simulation application and analysis are carried out. This method can evaluate the ability of the decoy against airborne magnetic detection, and can be used to evaluate the decoy and assist in optimizing the decoy use strategy.
