Abstract:

In order to promote the development of hard-target penetration initiation control technology, based on the hard-target penetration initiation control process, the development status of signal perception, signal processing and initiation control methods are reviewed. The theoretical results and numerical simulation results of penetration overload signal composition, warhead-fuze response and time-frequency characteristics are analyzed. The mixed signal processing, feature extraction and enhancement methods are summarized. The research status of new detection devices, filter materials and adaptive algorithm are reviewed. Through comprehensive analysis, the complexity of penetration overload signal and limitations of current initiation control technologies are revealed. In order to meet the development needs of penetration ammunition, it is important to master the change rules of overload under the constrains of projectile structure, target characteristics and penetration conditions, and to study the mechanism and processing method of multi-physical field signals, and composite sensing, information fusion and quick processing methods. The aim is to formulate a model-based initiation control strategy and independently recognize the process of the projectile penetrating a multi-layer hard target, thus forming an initiation control method with wider applications.
