Description

technical field

[0001] The invention relates to the technical field of ionospheric optical imaging, in particular to a method and device for automatic processing of ionospheric plasma bubble airglow images. Background technique

[0002] Optical observation method is an effective method for large-scale and low-cost observation of plasma bubbles in the ionosphere. The bubble has strong scientific significance and application value. It mainly obtains information such as plasma density and motion related to the emission intensity of the airglow by imaging and observing the airglow at a specific wavelength at the height of the ionosphere, which can reflect the ionospheric plasma The location, structure, size and movement speed of body bubbles and other information. The all-sky airglow imager uses narrow-band filters to extract the intensity information of airglow radiation in the characteristic height region of the middle and upper atmosphere, and uses a high-sensitivity CCD to ...
