Design And Implementation Of Anti-RCIED Broadband Wireless Communication Interference System

Radio Controlled Improvised Explosive Device,is an asymmetric weapon for terrorists to deal with countries around the world.The available communication system is complex and diverse.Remote controlled toys,walkie-talkies,GSM,maritime satellite phones with operating frequency below 2.5G have become available means of attack.In recent years,RCIED is becoming more widely been used by terrorists,illegal armed,organizations and individuals in order to make military confrontations,terrorists attack,turmoil and so on.The lawless people make use of RCIED to make a large number of terrorists attack,sanguinary conflict.They bring serious threaten to the life security of global military and civilian.The global governments are faced with new challenges.RCIED has become an unconventional weapon of great threats.It has been widely used in the partial war and conflicts areas around the world,and it has been a main way of asymmetric warfare.As an effective radio frequency jamming device against RCIED,broadband wireless communication jamming system must develop toward intellectualization diversification and miniaturization with the improvement of remote control improvised explosive device technology.Flexible working modes and multiple interference modes are required to be loaded on various platforms to work in a variety of scenarios.In this paper,an integrated broadband wireless communication jamming system is proposed,which can effectively jam RCIED.This paper completes the system functional requirements demonstration.The main application scenarios of the system are clarified.And the main technical indexes for different object systems are proposed: The accessibility analysis of system interference capability of different objects is carried out,which contain shortwave signal,ultrashort wave signal,mobile communication signal,maritime satellite signal and Wi-Fi signal.The overall framework and scheme design of the system is completed.The system hardware and software design is completed.The key technology of the system is conquered and mastered,includes the optimal interference for diversified communication systems,the high precision direct digital frequency synthesis technology,the miniaturized structural design and so on.Finally,the system is proved to meet the design requirements through test and verification.The overall function of the system includes:1)It can precisely aim at certain communication frequency.2)It can scan interference for a certain frequency band.3)It can block jamming to a certain frequency band.4)Multiple channels and multi-mode interferences can be worked at the same time.5)It can monitor the working state of each module in real time.6)It can flexibly and conveniently configure a variety required jamming modes.7)It can quickly select and call the pre-configured interference pattern.8)According to different application scenarios,mobile and portable products can be flexibly selected or combined.With the development of RCIED technology,it contains intelligent,diversified,miniaturized and other characteristics.The research results of this paper are based on the anti-RCIED wideband wireless communication jamming system,which can effectively interfere with the RCIED.The security of political,military,economic and the civilians can be protected effectively.
