ground range造句

• Based on mono - pulse radar system and the analysis of terrain echoes , a geometrical model of air to ground ranging is constituted . by using the signals received from the sum and difference channels of terrain follow radar , a group of the expressions for terrain echoes are educed and characteristics of these echoes are obtained . according to the characteristics of the echoes , the theory and method of pass zero detection of difference channel and its applications are discussed in detail
  针对一维单脉冲雷达体制，分析了地形目标回波特性；建立了地形跟随雷达空地测距的几何关系；利用雷达收发信号，导出了地形跟随雷达和差接收通道的回波信号表达式，进行了波形仿真，得到了地形跟随雷达的地面散射产生回波在时域中的特性；根据和差回波特性，阐述了差信号过零点检测测距的原理和方法及工程实践中的应用，并给出了真实雷达对外辐射试验的结果，验证了文中的仿真。
• Synthetic aperture radar ( sar ) has been widely used in both military affairs and civilian fields because of its high - resolution , independence of both time and weather conditions , etc . usually , sar could only be used to detect and image static targets instead of moving targets for the reason that the position drifting will make local mistake in the general sar image , which is usually caused by the velocity of the moving targets in the ground range direction , and when it comes to the target with strong scatter coefficient right in the drifting position , the moving target could not be detected at all
  合成孔径雷达( sar )由于其高分辨率、全天时、全天候等优良性能,已经在军事和民用领域得到越来越广泛的应用。通常,合成孔径雷达只能对静止目标进行检测和成像,动目标由于其径向速度而在常规sar图像中有一个位置偏移,使成像造成局部错误,而且当偏移处有强散射目标时,动目标将无法检测。军事上的应用也要求合成孔径雷达能对运动目标进行有效地检测和成像,因而运动目标检测( mti )及其成像日益成为合成孔径雷达领域研究的一个热点。
• This article is pointed out that the internal control system of our country commercial bank still is in stage newly established , and the internal control ground range international standard still has the equivalent distance , and the real effect is also too not ideal ? controlling the questions that exist in the system construction inside in accordance with our country commercial bank , and on the foundation to spirit that " the guide to the commercial bank internal control " according to the chinese people bank issuing is recently passed on and uses for reference the advanced interior accuse management practice experience of abroad commercial bank , this article puts forward building the tentative plan of pdca ' s internal control that fits our country national condition system o this tentative plan is stressed in the optimum research to realize the method of internal control system , and the substance is building the control system that the circular spiral moves upward of interior accuse policy decision - interior accuse execution - interior accuse control - interior accuse policy decision , ,
  本文通过对我国商业银行内部控制现状进行调查研究后指出，我国商业银行的内部控制体系还处于初级阶段，内部控制水平距离国际标准还有相当的距离，内部控制的实际效果也不太理想。针对我国商业银行内控体系建设中存在的问题，根据中国人民银行最近发布的《商业银行内部控制指引》所传达的精神并借鉴国外商业银行先进的内控管理实践经验，文章尝试把符合iso9002标准的质量管理方法( pdca循环方法)和内控制度建设结合起来，在此基础上提出建立一个符合我国国情的pdca内部控制体系的设想。该设想着重于内部控制体系最佳实现方式的研究，实质是建立一个以内控决策系统为中心，充分体现内控管理与监督，从内控决策? ?内控执行? ?内控监督? ?内控决策的不断循环螺旋上升的控制体系。
