This article examines an electronically scanned acousto-optic locator that is used for space diagnostics. Its primary mission is to collect data by remotely observing the atmosphere. During the study, the locator's structure and operating principles, signal acquisition, processing, and steering, and electronic scanning issues were examined. The object of the research is an electronically scanned acousto-optic locator, and its subject is the principles of forming acousto-optic signals, as well as the algorithms for electronic scanning and the operation of the locator under various conditions. The purpose of this work is the development and scientific justification of methods for atmospheric diagnostics based on a locator that can be used in the military sphere. Primarily, a physics-based mathematical modelling approach was used. Numerical modelling was also performed, and the system's performance was evaluated through experimental verification. The study of the interaction between acoustic and optical waves, the development of algorithms for scanning, and the subsequent verification of the system's performance enhance the significance of this work. The modelling takes into account factors such as wind, turbulence, vibration, and other external influences. The research has resulted in the development of a practically useful electronically scanned acousto-optic locator. This system operates rapidly even in changing weather conditions, has a spatial resolution of 20 meters - 30 meters, and a response time of less than 0.5 sec. It can operate at distances of 5 km - 6 km in difficult conditions and up to 9 km in normal conditions. Digital filtering and attenuation of additional signals further enhance the system's stability. The real-time vertical profiles of temperature and air density obtained by the system may be used to refine ballistic calculations and to adapt the trajectories of unmanned aerial vehicles.
