从遥远的地下掩体中发射的导弹,向上疾驶穿过云层,在大气之上急速飞行,在它打中目标之前没有机会能阻止这种再入导弹,除非能从自然的地球背景中或从它所施放的假目标杂乱的背景中把它识别出来。这种技术难题要求先进的技术来解决:多色焦平面阵列(FPAs)。所有的物体都有红外辐射 Missiles fired from distant underground bunkers swirling upward through the clouds and flying rapidly above the atmosphere had no chance of stopping the reentry missile until it hit the target unless it could be removed from the natural earth’s background or from its It is identified in the cluttered background of the fake pseudo-targets. This technical challenge requires advanced technology to solve: multicolor focal plane arrays (FPAs). All objects have infrared radiation
