洞库末端防护时对战术GPS制导武器干扰研究

Study on interfering tactical GPS guided weapons during terminal protection of caverns

为研究洞库末端防护时对战术级GPS制导武器的干扰问题,建立了洞库瞄准区模型和GPS制导武器末端干扰模型,分析了对巡航导弹和精确制导炸弹实施末端GPS干扰的可行性,计算了不同干扰概率下有效干扰GPS制导炸弹所需的GPS最小干扰距离,研究了单站、双站线形部署和双站三角形部署的最大防护角度和双站部署时的最佳站距,给出了多站防护洞库的部署方法。研究结果表明,GPS末端干扰的作战对象主要是空射GPS制导炸弹,在干扰有效时所需的GPS最小干扰距离S_(min)小于2倍的便携式GPS干扰站的作用距离R时,可采用扇形部署来防护洞库,且S_(min)越大,需要的干扰站的数量越多。但S_(min)>2R时,需要双层扇形部署多个干扰站,如对防护角度为160°的洞库,需要6个干扰站,其中外层均匀部署4个站,内层部署2个站。

In order to study the jamming of the terminal protection of caverns to tactical GPS guided weapons,this paper establishes a model of cavern aiming areas and a terminal jamming model of GPS guided weapons.The feasibility of terminal GPS jamming to cruise missiles and precision guided bombs is analyzed.The minimum GPS jamming distance required to interfere with the GPS guided bombs under different jamming probabilities is calculated.The maximum protection angles of the single-station linear deployment,two-station linear deployment and two-station triangle deployment are studied,the best station distance of the two-station deployment is analyzed,and the deployment method of multi-station protection of caverns is given.The results show that the combat object of GPS terminal jamming is mainly air-launched GPS guided bombs.During effective jamming,when the minimum jamming distance S_(min)required for GPS is less than twice the action distance R of the portable GPS jamming stations,sector deployment can be used to protect the cavern.The longer S_(min)is,the more jamming stations are needed.However,when S_(min)>2 R,multiple jamming stations need to be deployed in a double-layer sector.For example,for a cavern with a protection angle of 160°,six jamming stations are required,of which four stations are uniformly deployed in the outer layer and two stations are deployed in the inner layer.
