Description: The system of the automatic tracking of distance is intended for realization of automatic sentinel selection of radio is an impulse shadowing removed from an aim after distance, and also for the automatic measuring of distance to the aim. The system of the automatic tracking of distance is one of the major tracker systems be what zenithal rocket complex, that provides measuring of distance to the aim and aiming of zenithal rocket complex. The aim of the article is a choice of cost of the least digit of transformation a "code is a sentinel delay" and choice of parameters of algorithm of evaluation and extrapolation of distance of the digital system of the automatic tracking of distance. The digital systems of the automatic tracking of distance have high stability of parameters that does not depend on influence of environment. Except it during digital realization the system of the automatic tracking of distance considerably grows short running expenses, systems related to periodic regulation works. On the basis of research of mathematical model of the system of the automatic tracking of distance the analysis of firmness and quality of the system is conducted. Certain possible areas of parameters of algorithm are works of digital managing device, at that the system answers setting. Systematic and fluctuation errors are also expected, optimized parameters of algorithm on the criterion of minimum middling quadratic error, instrumental errors are appraised. Presented results of modulation and dependence over of middle square of error is brought on the parameters of algorithm, transitional description over of the system is brought. At the choice of parameters of the system, on the terms of her firmness, =0,141 =0,304 it maybe to provide the error of2K Т 1K determination of distance that does not exceed. Thus on results modulation were providing of requirement to the indexes of firmness and quality of the system of the automatic tracking of distance that fully satisfies to the requirements to such systems.


Keywords: digital control with auto maintenance target range, the mathematical model, the time discriminator, the Converter voltage-code Converter code-hour delay
