噪声场的时空相关数由于在抗干扰应用上的重要性,已引起人们的注意,并已做了一些理论和实验的研究。 噪声场时空相关函数的较早期工作是厄卡特作的,他建立了所讨论的空间内无噪声源时的时空相关函数所满足的微分方程组,从而导出了均匀各向同性噪声场的时空相关函数的表式。1962年,柯罗尼与谢曼就海水介质是均匀和无吸收的情况,计算了两种噪声模型的单频归一化空间相关函数。1966年,许祯镛采用传播网络算子工具,建立了所讨论区域内 Due to the importance of anti-jamming applications, the spatiotemporal correlations of noise fields have attracted people’s attention and some theoretical and experimental studies have been done. Earlier work on the spatiotemporal correlation function of noise field was done by Erkat. He established the differential equations satisfied by spatiotemporal correlation function in the space without noise and discussed the spatiotemporal correlation of homogeneous isotropic noise field Form of the function. In 1962, Coronie and Sherman calculated the single-frequency normalized spatial correlation function of the two noise models in terms of uniform and non-absorption of the seawater medium. In 1966, Xu Zhen 镛 using propagation network operator tools, the establishment of the region in question
