Industrial Automatic Control Systems and Controllers Annotation << Back Refi nement of the Contour of the Light Field of the Sector Complex on the Basis of the Method of Successive Images D.V. Vasiliev The article considers a new method for calculating the parameters of the contour of the light fi eld element of the sector navigation complex. It is based on the development and application, based on a comparison with existing engineering software systems, of ray tracing through optical systems and the currently used method for determining the range of visibility of light navigation signals based on the Allar equation, which is formally adopted in the main guidance documents on navigation equipment for air and water Transport. The mathematical apparatus of the proposed method is presented and the results of calculations confi rmed by a number of full-scale experiments that show a refi nement of the light fi eld contour, which amounts to 30% of the range of visibility of the fi re. The importance of this refi nement, directly affecting the main navigation parameters of the sector complex, was confirmed. Keywords: light fi eld; sequence of images; meteorological view; probability of detection; atmospheric turbulence; optical transfer function; modulation transfer function; phase transfer function; optical system.
