Research On Radar-communication Integration System Based On Chirped Spread-spectrum Techniques

In the modern airborne system, in the face of increasingly sophisticatedelectromagnetic environment and target threat, to explore and research comprehensiveintegration technology of many electronic equipment on modern battle platform,become a critical issues demanding prompt solution in modern high-tech war.A design scheme of integration signal based on chirped spread-spectrumtechniques is proposed and inplemented in this thesis combined with the currentsituation and the developing trend of the integration of radar and communicationsystem both at home and abroad, on the basis of Exploration and research in not orless impact on radar system performance, by thorough research on working principleof radar-communication integration system. Firstly, this thesis studies the differenceand similarity between Radar system and communication system, analysis thefeasibility design of radar-communication integration system.Secondly,combined withthe research of radar-communication integration both at home and aboard, involving aradar-communication integration design scheme based on signal integration, and thenthorough research and implement on working principle of radar-communicationintegration system. Finally, propose a deign scheme of integration signal based onchirped spread-spectrum techniques, expound the design of generation, separation anddata processing of integration signal and realize the computer simulation of the timedomain waveform and ambiguity function of the integration signal, and then thesimulation analysis of the radar system and communication system performance, showthat the integrated signal design based on chirped spread-spectrum techniques isfeasible, that will not or rarely affect radar system performance.
