摘要

上下文。空间控制雷达站承担着极其重要的功能,因此必须具有极高的可靠性,确保可靠性是其生命周期各个阶段的关键要求之一。目标。这项工作的目的是分析由于开发和制造监测空间的雷达站过程的特殊性而导致的确保可靠性的某些方面,证明利用国内开发人员的经验解决新样品可靠性问题的可能性。方法。对复杂技术系统的开发、制造和测试方法、现有标准和总设计师的标准进行了比较分析。结果。给出了空间控制雷达站的一些特点:唯一性、单一性、重复性低、量程大,不可能在厂家条件下直接制造和测试功能完整的系统。考虑到现行标准所没有的按照总设计人的标准进行设计和制造的一些特点,有必要制定新的考虑空间控制雷达站设计和制造具体情况的规范性文件。从应用的角度出发,提出了若干具体的科学和实际的解决办法,以确保国内开发商空间控制雷达站的可靠性,这些办法可用于进一步的发展。已经确定的是,现代可靠性理论中的许多术语没有一个应用焦点,并且不允许增加对物体状态分类的准确性。报告指出,在建立新一代空间监测雷达站的同时,还出现了科学上未知的新的科学和实际任务,这些任务的解决同新的科学思想的使用和各组成部分本身的发展有关。研究表明,在空间监测雷达的设计中使用同时基本基在确保各层次的可靠性方面造成了困难,因为现有标准只能对较低层次进行测试。现有的产品和雷达站的一般技术要求标准和控制和测试方法并不总是相同的,不可能确保采用高可靠的元件基础,我们将获得相同的雷达站可靠性。显然,确保可靠性的新阶段必须与元件本身的单个可靠性联系起来。它证明了在不可能应用传统控制的情况下,与选择现代一代雷达站的控制参数有关的科学任务的重要性,因为传统控制要求中断雷达站的操作。提出温度作为时间的函数作为估计产品状态的参数。在使用新信息信号的基础上确保新一代空间监测雷达站可靠性的若干方法,以及建立收集、储存和分析信息系统的元件基础内建的可靠性模型- -无线电电子设备的所有阶段都是如此。结论。考虑到空间监测雷达站的设计和制造特点以及国内开发商解决可靠性问题的实际经验,将确保创造高可靠性的几代空间控制雷达技术和发展“高度出厂准备”的雷达站。

Some features of the applied reliability of space control radar stations
Context. The space control radar stations carry out the extremely important functions, therefore, they must be extremely reliable, and ensuring reliability is one of the key requirements at all stages of their life cycle. Objective. The goal of the work is the analyzing some aspects of ensuring reliability, caused by the peculiarities of the process of developing and manufacturing radar stations monitoring space, justifying the possibility of using the experience of a domestic developer in solving reliability problems in new samples. Method. A comparative analysis of the methods of development, manufacturing and testing of complex technical systems, existing standards and the standard of the Chief Designer are used in the work. Results. Some of the characteristic features of space control radar stations are given: uniqueness, single production, low repeatability and a large range, the impossibility of manufacturing and testing functionally complete systems directly under the manufacturer’s conditions. A number of features of design and manufacturing according to the standard of the Main Designer, which are absent in the existing standards, are considered, the necessity of developing new regulatory documents that take into account the specifics of the design and manufacture of space control radar stations is justified. From an applied point of view, a number of specific scientific and practical solutions for ensuring the reliability of space control radar stations of a domestic developer which may be used in further developments are presented. It has been established that many terms in the modern theory of reliability do not have an applied focus and do not allow increasing the accuracy of classifying the state of an object. It is shown that the creation of new generations of space monitoring radar stations is accompanied by the emergence of new scientific and practical tasks unknown to science, the solution of which is connected with the use of new scientific ideas and with the own developments of component elements. It is shown that the use of co-temporal elemental base in the design of space monitoring radar creates difficulties in ensuring the reliability of hierarchical levels, since testing by existing standards is possible only for lower levels of hierarchy. It is established that the existing standards of general technical requirements and methods of control and testing for products and radar stations are not always identical and it is impossible to ensure, that applying a highly reliable element base, we shall receive the same radar station reliability. Obviously, the new stage of ensuring reliability must be associated with the individual reliability of the elements themselves. It justifies the importance of the scientific task associated with the choice of control parameters of the modern generation of radar stations in the conditions of the impossibility of applying traditional control, which requires the interruption of their operation. The temperature as a function of time is proposed as a parameter for estimating the state of products. A number of ways to ensure the reliability of new generations of space monitoring radar stations based on the use of new information signals, as well as reliability models built into the element base for creating a system for collecting, storing and analyzing information — the same for all stages of the radio electronic equipment. Conclusions. Taking into account the features of the design and manufacture of space monitoring radar stations and the practical experience of a domestic developer to solve reliability problems will ensure the creation of technology of highly reliable generations of space control radars and the development of stations of “high factory readiness”.
