对抗航空磁探的磁诱饵模拟指标分析及度量方法

针对航空磁探的威胁,潜艇可通过施放能够模拟其空中磁场特性的装置(磁诱饵)进行对抗，在对磁诱饵进行研究时,需要对其模拟需求进行分析。针对此问题,在对目前常用磁探仪工作原理及优缺点进行分析的基础上建立了基于标量磁探仪的航空磁探潜模型,以所建立的航空磁探潜模型为基础,分析了对抗航空磁探时磁源所需满足的模拟需求,并给出对抗效能评估度量方法及指标:磁场功率比、磁场方向可调性指标及有效面积指标,为潜艇空中磁场模拟方法研究的开展提供了基础。

Simulation Index Analysis and Measurement Method of Magnetic Decoy for Countering Aeronautic Magnetic Detection

To counter the threat of aeronautic magnetic detection , submarines can launch devices ( magnetic decoy) that cansimulate the aerial magnetic field characteristics , and hence the simulation requirements need to be analyzed in the process of stud-ying magnetic decoy. Aiming at this question, on the basis of analyzing the working principle, advantages and disadvantages ofcommonly used magnetic detectors, this paper establishes an aeronautic magnetic antisubmarine detection models based on scalarmagnetic detectors. Based on the estalished model, simulation requirements of magnetic source for counteriny magnetic detection areanalyzed, and the method and indexes of evaluating the countermeasure effectiveness which contain magnetic field power ratio, ad-justable index of magnetic field direction and effective area index are given, which provides a foundation for the research on themethod of simulating submarine'' S aerial magnetic field.
