Description

technical field [0001] The invention belongs to the technical field of photoelectric countermeasures, and in particular relates to an active lighting synchronous monitoring common-aperture follow-up and aiming launch system and method. Background technique [0002] The general feature of electro-optical countermeasures is to first realize the discovery and warning of targets. This process is generally realized by radar or electro-optical warning; secondly, the threat level sorting of the discovered targets and the identification of true and false targets are carried out, and the target orientation information is guided to the electro-optical countermeasures. Tracking and aiming equipment, this process is generally realized by the guidance of a large system or the tracking and targeting system itself has an alarm function; then the tracking and aiming equipment realizes accurate tracking and aiming of the target and emits anti-laser to irradiate the characteristic position of ...

Problems solved by technology

The current laser countermeasures can basically meet the requirements of photoelectric interference with low laser energy density, but it is difficult to achieve in the field of laser strikes that accurately strike a specific feature point of the target

Since the tracking and targeting launch system adopts full airspace protection and attack, and the existing laser technology cannot realize the placement of the overall laser and the tracking and targeting system inside the tracking and targeting launch turntable, the only way to guide the laser light into real-time random motion tracking and targeting In the system, this will lead to a real-time deviation between the tracking and aiming optical axis and the emitting optical axis due to structural deformation caused by the impact of adjustment limits and environmental changes. At the same time, due to the inherent tracking and aiming position deviation of the non-common caliber scheme Different two-axis deviations are caused at different distances, and these deviations are fatal for the countermeasures in the laser strike field that requires high energy density
