摘要
从直升机的作战任务出发,研究了射频隐蔽突防下的低可探测(LPD)平衡问题。首先,着重分析了无源探测系统对直升机隐蔽突防的威胁;然后,研究了相应的针对射频信号的低可探测措施;最后,通过仿真验证了低可探测技术使直升机隐蔽突防的效能提升,在采取低可探测措施后,被截获距离减少68%以上。
Starting from the combat mission of helicopters,this paper studied the problem of low probability of detection(LPD)balance under radio frequency covert penetration,focused on the threat of passive detection system to helicopter covert penetration,and studied the corresponding LPD measures for radio frequency signals.Finally,the simulation verified the effectiveness improvement of LPD technology to helicopter covert penetration.After taking LPD measures,the intercepted distance was reduced more than 68%.
