At first , the paper discusses the method of doppler parameter estimation based on raw datum , and analyzes the realization for range - doppler algorithm in real - time processing , motion compensation , datum subsection and geometry emendation . then , the corresponding system solution based on the algorithm is put forward . the versa module eurocard bus construction is adopted in the system design 本文首先讨论了基于原始数据的多普勒参数的估计方法，并且分析了距离多普勒算法在实时处理中的实现，以及实时成像下的运动补偿、数据分段及几何校正；然后在此算法的基础上提出了相应的系统解决方案，系统设计采用vme总线结构，其运算核心部分是一个由四片数字信号处理器组成的共享总线式并行处理模块，论文并提供了整个实时成像算法的软件实现。
The problem which we need to resolve is how to improve the test system reliability and open of wind tunnel test , and offer one test plane which it has high performance , such as use freely , maintain easily , etc . base on investigating several big wind tunnel test base in motherland , using for reference the excellence of the test system of wind tunnel test , combining several kinds of new technique , absorbing the experience , the text gives out one kind of design project , namly combine vxi bus and gui , form one new type wind tunnel test system 本文依据对国内几个大型的风洞实验基地的调研，借鉴国外风洞实验测试系统的优点，结合了几种较新的技术，吸收前人总结的经验的基础之上，提出了一种设计方案，即采用在vxi总线结构的模块式仪器组成测试系统的硬件部分，使用数据库与图形化编程环境相结合的方式研制开发测试系统的软件部分，将硬、软件这两部分连接起来，构建出一种新型的风洞实验测试系统。
At the same time the clock chip pcf8563 and serial eeprom chip csi24c01 with reset and wdt circuit of i2c bus are used hi the system . they have not only provided the non - volatility data storage area , the supervision ability of power supply and mcu and the rtc , and its i2c bus structure has been simplified the circuit design 同时在系统中还使用了护c总线结构的时钟芯片pcf8563和内置reset 、 wdt电路的串行eeprom芯片csi24coi ，它们不仅提供了电源和微控制器的监控功能、不挥发性的数据存储区、实时时钟，而且其护c总线结构简化了电路设计。
The appearance , concept and primary genres ( corba com / dcom and java / rmi ) of distributed object technology are discribed in brief , and then core a specification is discussed in detail in this paper . the advantages of corba , such as flexibility , platform - independent and extensibility , are analyzed in depth . these analysises demonstrate that corba is the best scheme to solve the problems such as cross - platform , cross - operation system , cross - language , cross - protocol and cross - edition in distributed systems , and corba is the principal specification to construct a software bus 然后，对corba标准规范进行着重介绍，并通过对corba的机构灵活性、软硬件平台无关性、系统可扩展性等优点的深入分析，论证了corba是目前解决分布式系统开发时所面临的跨平台、跨操作系统、跨语言、跨协议、跨版本等一系列问题的优化方案，是构建软件总线结构的首选标准。
This paper uses embedded internet technology , computer networking technology , power line data transferring technology , organically combines the tcp / ip basing computer networking architecture and plc basing bus architecture , import agent idea and finishes the designation , implementation and debugging of ia supervising system , which controls appliance through lan and internet in real time 本文采用嵌入式internet技术、计算机网络技术、电力线数据通信技术，将基于tcp ip协议的计算机网络结构与基于plc ( powerlinecommunication )的总线结构有机地结合起来，引入agent思想，构建了家电监控网络，进行了家电网络监控系统的硬件软件的设计、制作和调试，能实现在局域网乃至internet网上对家电的实时监控。
