Data storage and distribution system of hardware-in-the-loop radar simulation system

Abstract

The invention provides a data storage and distribution system of a hardware-in-the-loop radar simulation system. The data storage and distribution system of the hardware-in-the-loop radar simulation system comprises a bulk-storage memory board and reflective memory cards; the bulk-storage memory board and a radar signal processor of the hardware-in-the-loop radar simulation system are together inserted into one compact peripheral component interconnect (CPCI) case and mutually connected through low voltage differential signaling (LVDS) cables, and the reflective memory cards are combined with a computer main board through PMC ports and mutually connected with other reflective memory cards through optical fibers; the hardware-in-the-loop radar simulation system can simulate a specific system radar under laboratory conditions, test data that are output by the radar signal processor are real-timely stored to the bulk-storage memory board in the test process, meanwhile, the test data are real-timely reported to the reflective memory cards, and processed results are real-timely distributed to a radar efficiency simulation evaluation unit by means of the reflective memory cards. By means of the data storage and distribution system of the hardware-in-the-loop radar simulation system, the problem that large quantities of test data can not be real-timely stored in pre-stage test can be solved, and meanwhile, real-time sharing and transmission of data among all nodes in network can be achieved by means of topological structures of reflective memories.

Description

technical field [0001] The invention belongs to the technical field of radar simulation, in particular to a data storage and distribution system of a hardware-in-the-loop radar simulation system. Background technique [0002] Data collection and distribution are the key and necessary links in radar design and simulation. The data storage function mainly completes the collection of test data for later analysis and research of radar signal / data processing. The data distribution function is mainly used to report the results of radar processing to The data fusion center or command center completes subsequent processing. Since the large-capacity disk array storage tool can complete the real-time storage of massive test data, at present, the data storage in the actual radar mostly uses the disk array to complete the data collection, and carry out the detailed analysis of the data after the test is completed; the data distribution is mainly through the data storage The PowerPC emb...

AI Technical Summary

Problems solved by technology

[0003] In the simulation design of hardware-in-the-loop radar system under laboratory conditions, data storage and distribution are also faced. If disk array technology is used to realize data storage, it is relatively limited in terms of cost performance and operational flexibility. Research funds are limited under laboratory conditions, and it is uneconomical to invest most of the limited funds in the purchase of equipment; on the other hand, if disk array technology is used, it will undoubtedly increase the difficulty of system integration, including structure and data communication. Design, combining these two points, it is not advisable to use disk arrays to store test data in a laboratory environment
