本文用瞬时强度定义脉冲参量的方法,讨论了脉冲串通过随机介质后不同脉冲间的相关性。给出了脉冲能量相关函数的表达和算法,并在能量弱起伏的情况下,得到脉冲时间重心和脉冲宽度相关函数的近似表达。计算出能量相关函数,发现它是时间间膈的高斯型函数。能量相关时间随介质的相关时间增大而增大,随介质起伏强度增大而减小,并同发射脉冲宽度密切相关。
In this paper, the method of defining the pulse parameters with instantaneous intensity is discussed, and the correlation between different pulses after the pulse train passes through the random medium is discussed. The expression and algorithm of the pulse energy correlation function are given, and the approximate expression of the correlation function between pulse center of gravity and pulse width is obtained under weak energy fluctuation. The energy-related function was calculated and found to be a Gaussian function of the diaphragms in time. The energy-dependent time increases with the increase of the relevant time of the medium, decreases with the increase of the dielectric strength, and is closely related to the transmitted pulse width.
