The same procedure can be used to remove the graininess of highly enlarged photographs, which is of value e.g. in aerial photo reconnaissance. 同样的步骤可以用来去掉放大很多倍的照片上的颗粒特性,这在航空摄影侦察(PR)中是有价值的。
Considered the carrier and fight-plane as moving targets, the relationships between the effectiveness and the specifications of the photo, electron and radar reconnaissance satellites are put forward from the simulation results. 分别以大型舰船和飞机为探测目标,对光学侦察、电子侦察和雷达侦察等三种类型侦察卫星星座的技术性能指标和作战性能指标之间的关系进行了仿真分析。
