及时发现ARM袭击是采取各种后续抗反辐射导弹措施的前提.对ARM告警,有两种可行的思路:一是根据ARM与载机之间速度的差异,检测已脱离载机后高速运行的ARM;二是根据弹机分离时刻ARM的加速度特征,分离出强回波信号(ARM载机回波信号)附近的弱回波信号(ARM回波信号).两种方法各有优缺点.该文设计的抗ARM工作方式综合了上述两种方法的优点,通过加速度二次相位补偿后突出ARM回波信号,然后同时在跟踪距离门和其它距离门中探测ARM,以达到高的ARM发现概率.“,”Finding the attack of ARM in time is the precondition of taking the posterior measures to antagonize the ARM. There are two possible methods to find the attack of ARM: one is to detect directly the ARM flying in high speed after it leaves the carrier according to the speed difference between the ARM and the carrier, the other is to separate the weak echo signal(ARM echo signal) form the strong echo signal(the carrier echo signal) according to the acceleration characteristic of the ARM when it′s launched by ...
