本文系统而简要地评述了大气声遥感。与作者提出的将大气声学分为“经典的”和“现代的”两大范畴的观点相对应,大气声遥感亦可分为低层大气遥感和高层大气遥感两个方面:前者以可听声的主动遥感为主,其基础是大气“微观结构”对声波的散射;后者以次声的被动遥感为主,其基础是大气“宏观结构”对声波的折射。对这两大范畴,本文分别作了技术原理、仪器设备和主要观测等方面的概述。
This paper systematically and briefly reviews atmospheric acoustic remote sensing. Corresponding with the author’s point that atmospheric acoustics is divided into two categories, “classical” and “modern”, atmospheric acoustic remote sensing can be divided into two aspects: low-level atmospheric remote sensing and high-level atmospheric remote sensing: the former uses audible Active remote sensing based on the atmospheric “microstructure” of the scattering of sound waves; the latter passive infrasound-based infrasound, which is based on atmospheric “macro-structure” of the refraction of sound waves. For these two categories, this paper gives an overview of the technical principles, equipment and main observations.
