Design And Implementation Of Vehicle-signal Frequency Jamming System

RCIED(Radio Controlled Improvised Explosive Device)is a device consist of transmitter and receptor,It is an asymmetric weapon deal with American by terrorists,and now,it become the most dangerous weapon used by terrorists and extremists which can be a threat for world-wild civilians and armies.RCIED materials probably consist of commercial,military and self-made shells or shell parts.IT is popular used in bomb attacks due to low cost,not easy to invesigation and simple for material get.The RCIED mode of initiation is mainly transmitted from the transmitting device to the receiving device,and the receiving device is modified to send the signal to the explosive device(such as electric fuse).This kind of attack mode is widely used in the area of the conflict of the local war and the unstable social order.Due to the growing intensity of the RCIED attacks,many countries include in American,South Africa,France,Turkey and other countries consider a interference technology research to against RCIED,and developed out of the vehicle jamming system,put into actual combat.But according to statistic results,Duke V2 and Warlock jamming system of American,hunter jamming system of Israel etc,their pulse only covers a small range of frequency bands,and now,a wide range of interference system haven't been created in this world.BY summarizing the study of similar products,this paper according to the propsoed user's requiements,considering out the vehicle-signal frequency jamming system,after full argument,analysis,design,optimization and a series of basic work,designing and implementation of the vehicle-signal frequency jamming system.This system includes the following aspects of the content:a).Obtaining the key technologies in the field of broadband wireless communications interference and the Anti-RCIED vehicle-signal frequency jamming system can be used in to actual battlefield.b).Obtaining the main technology of vehicle modification,including the force balance calculation,wind resistance calculation,the layout of the vehicle and other major modification technology.c).The original design of the inside shock absorber cabinet,effectively solve the problems for equipment about weight,large size of the vehicle with narrow space.d).Through the system designing,space layout designing to solve among the antenna interference rejection,enabling the system to a range of 20MHz-2500 MHz toys remote control,radios,mobile phones,satellite phones,WI-FI and other wireless communication equipment implementation of blanket jamming,blocking terrorists use RCIED remote detonate signal by restructuring them,effective response to all kinds of terrorist attacks.e).Analysing,simulating,calculating the safety for antenna platform of vehicle roof in normal and high speed.f).Compact product structure,the use of low power consumption,modular,ergonomic design,easy to use and maintenance,high reliability,in the need to interfere with special frequency bands,you can achieve the effect of interference though hardware upgrades.This subject acquire vehicle broadband frequency interference system prototype.it's effects radius greater than 250 m,frequency range of 20MHz~2500MHz,some indexes are as follows...
