Description
technical field [0001] The invention relates to a device for simulating sea surface atmospheric turbulence. Background technique [0002] In the process of laser transmission on the sea, the laser beam is not only absorbed and scattered by the atmosphere, but also affected by the refraction of the atmosphere. Due to the influence of factors such as temperature gradients and pressure gradients inside the atmosphere, the atmosphere moves irregularly and randomly in both horizontal and vertical directions, forming atmospheric turbulence. Atmospheric turbulence causes the refractive index of the atmosphere not only to be unevenly distributed in space, but also to randomly and dynamically change over time, resulting in dynamic distortion of the wavefront (ie, phase) of the beam during propagation. Under the influence of atmospheric turbulence, the laser beam will appear flickering, drifting, and fluctuations in the angle of arrival. Compared with atmospheric turbulence on land,...
