摘要
对浅海目标辐射噪声的矢量场特性和矢量噪声测量技术的相对优势开展了实验研究,对实测数据进行了相关的矢量信号的处理与分析。测试结果表明,目标辐射噪声矢量场相关性很强;与传统标量测量方法相比,在浅海低信噪比条件下,矢量法有效提高了目标辐射噪声测量增益。
The vector field characteristic and comparative advantage of vector noise measurement technique of the radiated noise originated from target in shallow sea were studied through measurement. The measured data were processed and analyzed by vector method. The test result showed that the vector field of target radiated noise is highly relevant; the vector method can effectively improve the gain of target radiated noise measurement, particularly in shallow sea of low-SNR.
