摘要: 由于混响因素的影响使得主动声自导方式下鱼雷对航行自噪声的获取十分困难, 使得准确测量鱼雷自噪声成为困扰鱼雷自导系统的难题之一。针对此, 文章提出一种主动声自导带着混响测量鱼雷航行自噪声的测量方法, 详细介绍了该方法的原理并进行了计算, 通过自噪声测量方法示例, 证明了其可行性。试验证明, 该方法灵活、机动, 既可以测量换能器单元所接收到的噪声, 也可以测量波束输出的束内噪声, 并可做到实时、实地、实雷测量, 降低了成本, 提高了效益, 为准确测量鱼雷航行自噪声提供了新的技术途径。Abstract: The effect of reverberation makes it very difficult for a torpedo to acquire its self-noise under active homing mode, therefore, a measurement method of torpedo self-noise with reverberation during torpedo running under active homing mode is presented in this paper. The principle of the method is introduced, and computations are conducted. Experimental result verifies its feasibility. Both the noise received by transducer elements and the noise in transmitted beams can be measured by this method with flexibility, real-time, and low cost. And the self-noise while performing the task of torpedo trial can also be measured by this method.
