Ranging is the most essential function of radar , however , high - precision ranging , especially the short range , is an important application field of civil radar 测距是雷达最为基本的功能,而高精度测距,特别是近程高精度测距是雷达的重要民用领域。
One is minimum of cost and the other is maximum of gross benefit . because the product precision influences its price , the precision ranges under these two conditions are selected 主要考虑到产品的精度指标对产品的销售价格的影响,分别取得这两种情况下的产品的精度指标。
The paper also bring out using a special structure serial , the concatenate serial , to measure with double precision range , and at the same time realizing high speed ss communication with tamed - ss technology 创造性地提出应用特殊结构序列-链接序列进行双精度、双量程测距,并同时应用软扩频技术实现高速率扩频通信。
In contrast with the precision range obtained by the fuzzy mathematics compositive evaluating model , the enterprise can choose the optimum design scheme , and at the same time it can be the reference to quoted price of new products 再利用模糊综合评判模型取得的精度指标与产品精度值的对应关系,它可以帮助企业选择最佳的设计方案,同时又可以作为企业新产品报价的参考。
A manufacturing cost model is built . it is made up of normal manufacturing cost and additional influencing factors . the influence of product precision range , manufacturing batch and manufacturing period etc on product cost are analyzed mainly 本模型重点分析了精度指标、生产批量、生产周期等不同影响因素对制造成本的影响,得出制造成本对精度指标在一定范围内变化不基于plm模式下的产品成本模型与优化敏感这一结果。
According to the features of precision , efficiency , inspection dimension and accuracy varying great range , designed closed - loop control system composition of servomechanism and grating to assure system ’ s precision , smooth , efficiency , and to realize the great dimension range measurement ; designed image capture system composition of ccd , automatic variable power lens and self - adaptive lighting , to realize integration of large inspection precision range ; designed electric control and software system to make the inspection convenience and fast . finally , developed the prototype instrument 针对微电子产品视觉检测的精密、高效、检测精度和测量范围变换大的特点,设计了伺服驱动、精密光栅采集组成闭环控制系统以保证运动精密、平稳、高效,和大的尺寸测量范围;设计了由ccd摄像机、大范围自动变倍镜头和自适应光源组成的图像采集系统,集不同精度等级的检测于一体;设计了电气控制和软件系统使检测方便快捷。
