世界各国在近年来开发和使用的新型猎雷声呐,如变深声呐、侧扫声呐、合成孔径声呐等,使水雷障碍面临严峻挑战。为提高水雷障碍在作战条件下的稳定性,可以利用声反射体模拟真实水雷的目标强度,干扰猎雷作业。研究了在低频条件下,声反射体外形、材料等因素对目标强度的影响,并进行了初步验证,为水雷假目标的论证和设计提供了理论依据。
In recent years, all countries in the world have developed and used new types of hunting nets, such as deep sonar, side-scan sonar, and synthetic aperture sonar, which pose harsh obstacles to the mine. In order to improve the stability of the mine obstacle under the operational conditions, it is possible to use the acoustic reflector to simulate the target intensity of the real mine and interfere with the mine hunting operation. The effect of the shape and material of the acoustic reflector on the target strength under low frequency conditions was studied and the preliminary verification was carried out. This provides a theoretical basis for the demonstration and design of the mimicry target.
