Abstract

Subject of study. This study considers controllable on-board combined optoelectronic devices with dynamic errors in their tracking and image stabilization systems depending on the atmosphere parameters, characteristics, and probability of surveillance task execution. Aim of study. The study aims to derive analytical dependences for the assessment of tolerance on the accuracy of control and image stabilization of on-board combined optoelectronic devices. Method. In order to obtain the required tolerance, we used a frequency method for the assessment of the image quality based on the modulation transfer function of the optoelectronic system depending on the modulation transfer functions of the atmosphere, objective, photodetector, and amplifier–transformer that, in turn, depend on the radiation wavelengths and spatial frequencies of resolution. The following inverse problem was solved: Equations for the assessment of tolerance on the accuracy of control of the subsystems ensuring tracking and image stabilization were obtained based on the admissible modulation transfer function of the optoelectronic system. Main results. Analytical dependences were derived and a graphical analysis algorithm was proposed for the evaluation of tolerance on the accuracy of systems for control and image stabilization of the on-board combined optoelectronic device. An example of the calculation of the tolerance on the accuracy of control and image stabilization was presented. Practical significance. The obtained results enabled the correct analysis and synthesis of algorithms for control, modeling, and testing of systems for vibration protection and automated control of on-board combined optoelectronic devices.
