水下航行体目标成像及处理研究

现代海战水下作战环境变得越来越复杂，为了提高作战效能，有必要提高水下航行体自导系统的目标识别能力．为了提取目标的本质特征，构建目标的水声图像，采用正交解调、复数字波束形成、波束内插、图像处理等技术，形成水下航行体目标图像．该图像为水下航行体在复杂作战环境下识别目标关键部位，并对目标实现精确打击奠定了技术基础．实验结果表明，该方法在实际中切实可行．

Study of target acoustical imaging and processing used in the underwater vehicle

Underwater combat fields are complex in modern sea environment. In order to improve an operational efficiency, it is necessary to improve the ability of target identification in the underwater vehicle homing system. Main composing and implementation method of acoustic imaging are introduced in this paper, which is used in the underwater vehicle. Real characteristics of a target will be obtained for forming the acoustical image of the target. Quadrature demodulation, plural multi-beam formation, beam-forming interpolation, image processing technology are used to form the acoustic image, which helps the underwater vehicle to recognize the crucial part of the target in complex combat fields, which lay a solid foundation for the underwater vehicle to attack the target effectively.
