A Study Of The Technology Of The Networked Radar Anti-jamming By The Simulation

Compared with the single radar system, the networked radar system with a greaterdetection range, higher detection performance has gradually become an importantdirection of the development of radar systems. Simultaneously, the jamming technologyof the networked radar research being carried out, so the networked radar anti-jammingtechnology research is of great significance to enhance the anti-jamming capability andimprove the performance of the networked radar detection, in the complex environment.In this thesis, we researched the network radar anti-jamming technology.Researched the networked radar anti-jamming assessment indicator, optimize thedeployment of the radars’ station in the network, the anti-jamming way of the signalprocessing and polarization characteristics extraction against the typical distributedrepression and deception jamming, the main contents are as follows:1. Researched and analyzed the current situation and development trends of thenetworked radar and its anti-jamming technology, the characteristics and mechanismof the typical measures of jamming for the networked radar.2. We researched the mathematical model of the airspace coverage and the detectionperformance of the networked radars’ optimal deployment. And according to therequirements of the principle of the number of the networked radars’ optimaldeployment, we researched specifically (in the different configurations of thenetworked radar, the reasonable value of the number of radars).3. Analyzed the mechanism of the distributed jamming, on the one hand, weresearched when the networked radar with distributed jamming, its detection areachanged by receive coherent; on the other hand, we used the Multiple HypothesisTracking (MHT) to applying in the networked radar against the distributedrepressive jamming; and simulation.4. Based upon the distributed deception jamming of the DRFM (digital radio frequencymemory), we researched its different characteristics and mechanism. According tothe polarization characteristics, we researched the method of against the distributeddeception jamming of the DRFM, and simulation. In this thesis, researched the networked radars’ method of anti-jamming by thenetworked radars’ optimal deployment, the networked radars’ information fusion, thepolarization characteristics of the targets, et al, and simulated to test their effects.
