Embodiment Construction

[0037] According to the following Figure 1 to Figure 5 , the preferred embodiment of the present invention is described in detail.

[0038] The conference paper "Research on Software Reliability Testing Method" discusses the importance of software reliability testing, analyzes the purpose and testing characteristics of software reliability testing, and expounds the specific steps of software reliability testing. The method and steps of software reliability testing proposed in this paper can be extended to reliability testing of the whole system.

[0039]When modeling the operation structure diagram of the system, the invention fully combines the modularization and hierarchical features of the phased array antenna system, abstracts the functions of the system from the top-level module, and gradually refines it to a single operation. When collecting logs, it is mentioned in "Research on Service-Oriented Software System Usage Profile Construction Method" to select a log time pe...

Abstract

Provided in the invention is a reliability test method for a beam control system of a phased array antenna. An operational structure diagram of a tested system with a tested version is constructed andall operational flows are generated; the usage probability of the operational flow of a system with a previous version is calculated and the usage probability of the operational flow of the system with a previous version is used as the usage probability of the operational flow of the system with the tested version in optimal matching; according to the generated operational flow and the calculatedusage probability of the operational flow, a test case of a phased array antenna beam control system is generated; and reliability testing of the phased array antenna beam control system is performedbased on the test case. Therefore, the e test accuracy and the test efficiency are improved; the factors affecting the reliability in the system can be discovered rapidly; the reliability level of the product is rapidly increased; and the development cycle is shortened.

Description

technical field [0001] The invention relates to the field of phased array antennas, in particular to a reliability testing method of a phased array antenna beam control system. Background technique [0002] Compared with traditional scanning antennas, phased array antennas have the advantages of rich functions, light weight, fast beam scanning, and high precision. They are more and more widely used in the field of satellite payloads. With the increasingly rich functions of phased array antenna systems, Its complexity and development cost have shown rapid growth, and the reliability problem of the entire phased array antenna system has become more and more prominent. Therefore, the reliability of the phased array antenna system is tested to evaluate the reliability level of the system and find that it affects the reliability of the system. It is more and more important to make the reliability of the whole system grow rapidly. [0003] The patent "A Reliability Testing Method...
