50997 研究可为反临空高速目标的探测跟踪系统发展提供理论和技术支持。 Research for the detection of airport high-speed target tracking system development to provide theoretical and technical support.
50998 针对运动目标的无源雷达成像，给出一种采用分布式接收孔径的成像方法。 For passive radar imaging of moving targets, a method of using distributed receiving aperture imaging.
50999 首先建立运动目标的回波信号模型，该模型无需任何发射源先验信息。 First to establish a moving target echo signal model, the model without any a priori information source.
51000 而后基于分布式孔径接收到的回波数据稀少，以目标位置和速度为未知量采用广义似然比检验的方法进行成像，完成成像区域内运动目标的成像和速度估计。 And then based on the distributed aperture receives the echo data is scarce, target position and velocity as unknown quantity using the generalized likelihood ratio test methods for imaging, imaging of moving targets in the area of imaging and speed estimation.
51001 最后以WiMAX信号作为机会照射源进行仿真分析，结果表明所用方法能够有效实现无源雷达动目标成像。 WiMAX signal as the last chance irradiation source simulation analysis, the results show that the method can effectively realize the dynamic target of passive radar imaging.
51002 针对长期贮存复杂可修系统的特点，提出一种以可用度为约束的系统贮存寿命评估方法。 According to the characteristics of the long-term storage of complex repairable system, puts forward a system based on constraints of availability for storage life evaluation methods.
51003 该贮存系统由三类部件串联构成: The storage system consists of three components in series:
51004 第一类部件为高可靠产品，具有给定故障时间分布且不进行检测; the first part is highly reliable product, with the given fault time distribution and testing;
51005 第二类部件为等时定检维修产品，且修复如新; The second part for missile d etection maintenance products, such as repair as new;
51006 第三类部件为定期预防性更换产品，更换周期与检测周期相同。 The third type of components for regular preventive replacement products, change cycle is the same as the test cycle.
