烟幕干扰弹主要通过化学燃烧或爆炸分散形成烟幕或气溶胶云团，在目标前方特定空域 形成遮蔽，干扰敌方导弹，具有成本低、效费比高等优点。随着烟幕干扰技术的不断发展， 现已有多种投放方式完成烟幕干扰弹的定点精确抛撒，即在抛撒前能精确控制烟幕干扰弹到 达预定位置，通过时间引信时序控制起爆时间。 现考虑运用无人机完成烟幕干扰弹的投放策略问题。具有长续航能力的无人机挂载某型 烟幕干扰弹在特定空域巡飞，受领任务后，无人机投放烟幕干扰弹在来袭武器和保护目标之 间形成烟幕遮蔽。每架无人机投放两枚烟幕干扰弹至少间隔1 s。烟幕干扰弹脱离无人机后， 在重力作用下运动。烟幕干扰弹起爆后瞬时形成球状烟幕云团，由于采用特定技术，该烟幕 云团以3 m/s的速度匀速下沉。据试验数据知，云团中心10 m范围内的烟幕浓度在起爆20 s 内可为目标提供有效遮蔽。 来袭武器为空地导弹，该型导弹飞行速度300 m/s。导弹的飞行方向直指一个为掩护某 半径7 m、高10 m的圆柱形固定目标而专门设置的假目标。以假目标为原点，水平面为 𝑥𝑦 平面，真目标下底面的圆心为 (0,200,0)。警戒雷达发现来袭导弹时，3 枚导弹 M1、M2、 M3分别位于 (20000,0,2000)、(19000,600,2100)、(18000,−600,1900)；5 架无人机的位 置信息分别为 FY1(17800,0,1800)、FY2(12000,1400,1400)、FY3(6000,−3000,700)、 FY4(11000,2000,1800)、FY5(13000,−2000,1300)。 在导弹来袭过程中，通过投放烟幕干扰弹尽量避免来袭导弹发现真目标。控制中心在警 戒雷达发现目标时，立即向无人机指派任务。无人机受领任务后，可根据需要瞬时调整飞行 方向，然后以70~140 m/s的速度等高度匀速直线飞行。每架无人机的航向、速度可不相同， 但一旦确定就不再调整。 为实现更为有效的烟幕干扰效果，需设计烟幕干扰弹的投放策略，主要包括无人机飞行 方向、飞行速度、烟幕干扰弹投放点、烟幕干扰弹起爆点等。请建立数学模型，针对不同情 形，分别设计烟幕干扰弹的投放策略，使得多枚烟幕干扰弹对真目标的有效遮蔽时间尽可能 长。不同烟幕干扰弹的遮蔽可不连续。 问题1 利用无人机FY1投放1枚烟幕干扰弹实施对M1的干扰，若FY1以120 m/s的 速度朝向假目标方向飞行，受领任务1.5 s后即投放1枚烟幕干扰弹，间隔3.6 s后起爆。请 给出烟幕干扰弹对M1的有效遮蔽时长。
