Buzovskyi D. Development of method to control ship's position by the multiposition radar system

The dissertation is dedicated to the actual problem of the development high accuracy multiposition radar system consisted of certain amount of the radar stations which are located in designated positions in relation to each other. To optimize the structure of the multiposition radar system when accuracy characteristics of measured by the stations distance and bearing and number of the stations are designated it is necessary to place the radar stations so that to obtain the minimum value of scalar criterion of accuracy (variance of position error). It is shown that development of analytical procedure to take into account the limitations in disposition of the radar stations of the system requires cumbersome and laborious calculations. This reason stipulated development of the simulation model to choose the optimal structure of the multiposition radar system, using the electronic charts of the designated area. In this case the optimal structure of the system of the radar stations is generated by a developer with assistance of the simulation model. The detailed description of simulation model of the dissertation work realized as a software product is described. The analysis of possibilities to equip approaches to the port of Feodosiya with a multiposition radar systems consisted up to six radar stations is done in the work. The accuracy evaluation and positive conclusion in regard to the offered structure of the radar equipment are obtained.
