DS/FH Systems Design And Implementation Of Automatic Test Immunity

With strong security and anti-jamming characteristics, Frequency-Hopping Spread-Spectrum(FHSS) is more and more widely used in military and civil communication applications. In this paper, for the system simulation, test methods research, DS/FH anti-jamming Automatic Test System for these three aspects of the entire DS/FH anti-jamming automatic test system conducted in-depth research, and finally through the entire test verification system automatic test system meets the technical requirements.Through research, testing and simulation, design of system based on universal test instruments and software radio technology communication device interference immunity performance. The means test will be applied to form a variety of wave interference immunity performance of the device under test, additional research will be accurately scaled special or general actuator, interference sources and monitoring equipment, so that the test data with higher reliability and consistency.In the design of the entire system on the first systematic study of the simulation, the simulation is divided into two portions and frequency hopping spread spectrum system systems are direct sequence spread spectrum system performance simulation systems and frequency hopping systems performance simulation system, simulation system of Digital Communication basis, using Matlab algorithm platform of simulation algorithms and software design, build simulation system. In this paper, the simulation system implementation method are described, and simulation analysis, the simulation conclusion, the method of preparation and follow-up of the system set up to establish a theoretical and technical basis. At the same time, the results of the simulation system can be used as the theoretical basis for further verification test methods and test systems. In accordance with the conclusions simulation, test methods were studied to finalize the seven technical specifications and corresponding test methods. By determining the simulation analysis and testing methods, as a basis for designing DS / FH jamming Automatic Test System. Finally, to verify the functionality of the system through the system test, performance meets the technical requirements.The result shows that this test facility has relatively wide generality and applicability, featuring wide bandwidth coverage, low measurement uncertainty, high system integration, good repeatability and reliability, fast and easy measuring process.
