F-22隐身战斗机为了在作战中实现真正意义上的战术"隐身",没有装备传统的有源干扰机和大功率搜索雷达,所装备的ALR-94无源系统成了检测、跟踪甚至攻击目标的关键设备,探测距离达463km,而其APG-77有源电扫描阵列雷达,能有节制地用很窄的似"激光波束"探测目标,信号强度、延续时间和空间形状严格受辐射管理,必要时还能产生大功率干扰波束,简直成了能干扰雷达的有源压制干扰机.F-22也因此摆脱了传统的电子战作战模式,进行一种创新概念的电子战,没有电子干扰(攻击)设备的电子战. 相似文献

在老乌鸦协会技术讨论会26届年会上,美三军高级官员向电子战专家们提出忠告:①为了能在未来冲突中更好地保存自己,避免被敌方检测非常重要。②研制与生产不要同时进行。③自卫电子战原理应用到坦克上。空军中将J·Adams说:空军没有得到等值的电子战设备。在过去8年里空军化了220亿美元(部分原因是研制和生产同时进行),结果某些电子战设备不能达标,这迫使空军修改了它的自卫原则。例如采用隐身技术的部分原因是电子战设备对威胁没有足 相似文献

Space science missions are increasingly challenged today: in ambition, by increasingly sophisticated hypotheses tested; in development, by the increasing complexity of advanced technologies; in budgeting, by the decline of flagship-class mission opportunities; in management, by expectations for breakthrough science despite a risk-averse programmatic climate; and in planning, by increasing competition for scarce resources. How are the space-science missions of tomorrow being formulated? The paper describes the JPL Innovation Foundry, created in 2011, to respond to this evolving context. The Foundry integrates methods, tools, and experts that span the mission concept lifecycle. Grounded in JPL's heritage of missions, flight instruments, mission proposals, and concept innovation, the Foundry seeks to provide continuity of support and cost-effective, on-call access to the right domain experts at the right time, as science definition teams and Principal Investigators mature mission ideas from “cocktail napkin” to PDR. The Foundry blends JPL capabilities in proposal development and concurrent engineering, including Team X, with new approaches for open-ended concept exploration in earlier, cost-constrained phases, and with ongoing research and technology projects. It applies complexity and cost models, project-formulation lessons learned, and strategy analyses appropriate to each level of concept maturity. The Foundry is organizationally integrated with JPL formulation program offices; staffed by JPL's line organizations for engineering, science, and costing; and overseen by senior Laboratory leaders to assure experienced coordination and review. Incubation of each concept is tailored depending on its maturity and proposal history, and its highest-leverage modeling and analysis needs. 相似文献
