我们考虑了随机Schrödinger方程解的时空维格纳变换在白噪声极限和高频条件下。我们特别分析了强横向分集极限下时空维格纳变换的弱确定性。我们还展示了如何在随机介质中的宽带阵列成像中使用这些渐近结果。
We consider the space-time Wigner transform of the solution of the random Schrödinger equation in the white noise limit and for high frequencies. We analyze in particular the strong lateral diversity limit in which the space-time Wigner transform becomes weakly deterministic. We also show how to use these asymptotic results in broadband array imaging in random media.
