Building The Model Of RF Stealth Systems And Simlation Analysis Of RF Stealth

The most important in the modern war is able to grasp the information of the enemy in all aspects,and let the enemy cannot get our information.ecpect get the information before the war,collecting information in the war is also very important.With the development of the passive detection technology,the Radar survival Environment will suffer more threat.In order to improve the survival probability of radar,it is important to explore the radar's stealth performance.The RF stealth is a new research direction in China,at present,the focus of RF stealth is still in the research of LPI signal,power control,and evaluation means.However,It was not enough for RF stealth if only study in one direction,if we want to get low intercept devices with excellent performance,the RF stealth need a more systematic and comprehensive study.Therefore,the domestic research in these areas was waiting for Strengthen.In this paper,firstly,it had introduced the development process of RF stealth.Secondly,the article described how to model the signal transmitting system in detail,the modeling was Containing Launch system,space environment,intercept receiver three Sub module.In this part,it had introduced six kind of Intercept receiver,which extracted six kind of Intercept receiver the working principle.so it was convenient to using in the simulation modeling of program.After that the article had given some of the result of signal's identification evaluation and Sorting algorithm,a sorting module had building in the simulation software.When you input the signal and noise into the model,you can got the recognition accuracy of the signal.Lastly,in the base of sum up the research data,Had getting the way how to reduce the Interception probability of the Radar systems,the difference of interception in data chain and radar system had be discussed also.In the four chapter.the characteristics of radar and data link systems in RF stealth performance were analyzed,which was a major innovation in this paper.Through the study,it was found that a single interception strategy can reduce the interception probability from 10 to10~7 times,so the influence of each parameter on the RF stealth was very huge.In addition,the effects of different types of signals and different types of interception receivers on the performance of the radio frequency stealth were also taken into account.It was found that the interception probability between different basic signals can reach more than 300 times,and the interception characteristics of the intercepted receivers were also show Tremendous differently,it was determined by their inherent properties.In this paper,it was analyzed the RF stealth system,and the interception analysis under the radar and data chain system was given.By the low interception strategy,the intercept probability of radar can be reduced by 1000 times in the same circumstance of detection distance.At the same circumstance,it was found that the interception probability of the data chain is 70dB lower than that of the radar system.After that,some ground effects were also taken into consideration.Finally,all modules were encapsulated into a software,and the software was tested,so all the designs were completed.
