In the former version of mdsl system , the record - unit is based on dos that is not real time os , so to enhance the reliability of system in all rates of input data flow we redeveloped the system based on the qnx , which is an excellent real time os 由于在以前的开发产品中用于记录语音和雷达数据的记录单元采用的是非实时操作系统,为提高系统在提高记录仪系统的实时性,提高系统在各种数据输入流量下的可靠性,我们在实时操作系统qnx下对整个系统进行了重新开发。
The aim is to find a way to explore both the spectral advantage of multispetral data and the ability of high spatial resolution image toreflect details and update big scale map . sar data may be utilized as supplement of optical data under bad weather conditions in austral areas 目的是探索在南方地区,如何充分发挥tm etm +影像在光谱分辨率上的优势和高分辨率卫星影像在刻画细节、大比例尺图件更新中的能力、以及云雨条件下利用雷达数据补充光学数据不足的方法。
Because the radar data processing is quite professional , so it is very difficult to find any other similar software and any related material . after studying the flow of radar data processing and analyzing the requirement of the multi - radar data fusing for a long time , i have designed and completed the multi - radar testing data simulative software 由于雷达数据处理的专业性较强,因此在国内找不到其他成熟的类似软件可以借鉴,而且也难以找到相关的资料,我在研究了雷达处理的相关流程后,针对雷达数据处理的测试需求,开发了“多雷达数据模拟软件” 。
Previous data had given the search for lunar ice a boost , including 1992 radar data indicating ice deep in craters at the poles of mercury , 1996 radio data from the moon taken by the clementine orbiter , and the lunar prospector orbiter ' s 1998 discovery of an elevated amount of hydrogen at the lunar poles 早先的数据推动了月球冰的搜索,包括1992年雷达数据显示在墨丘利环形山深处的冰, 1996年克莱门汀轨道器采集的月球雷达数据,以及月球勘测者1998年发现的月球两极氢数量的提升。
The same target will appear two courses on the electronic chart for the errors of the two sensors are statistically independent . the paper mainly includes two points : ( 1 ) study the fusion between ais data and radar data in vts ; first the paper discusses the kalman filter of the target ' s tracking . on the basis of which we study the data fusion between the track of radar target and that of ais target 对于雷达目标的航迹,选择雷达作为位置传感器,对于ais目标,选择gps (全球定位系统)接收机作为位置传感器,由于测量雷达航迹和ais航迹的传感器是不同的,两种传感器误差是相互独立的,这样在海图上显示目标的时候出现对于同一目标出现不同的航迹,本研究的重点包括两个方面: ( 1 )研究vts系统中ais数据和雷达数据的融合:首先讨论目标航迹的kalman滤波,在目标航迹kalman滤波的基础上对雷达目标和ais目标的航迹进行数据融合的研究;同时本研究将对ais的位置传感器分差分gps和非差分gps两种情况进行分析和处理。
And the last part summarizes the design of doppler weather radar second production net - server process platform , we get a feasibility project that how to share radar - data online . this network database system possess ability for radar ' s basic date share online , it include download product module , data file manager , compress transmit , image display net - database ( add , query , delete and download ) . and introduce the material technique on how to realize the platform system 通过对一个基于多普勒天气雷达二次产品处理系统网络应用的设计,探讨了经过处理后的雷达数据如何在网络上共享的一个可行性方案,在这基础上设计实现了一个具有基本数据资料共享能力的网络数据库平台,包含了在线下载产品模块,数据文件管理,压缩传输,图像显示,网络数据库(资料的入库、查询、删除和下载) ,并就具体的技术实现做了介绍和探讨。
The dissertation introduces the background of radar data transmission in special environment , and proposes a method of pci interface based on fpga ipcore , then particularly discusses its system structure and its internal function module , additionally accomplishes its driver program with windows driver model ( wdm ) 本文介绍了特定环境下雷达数据的传输背景,提出了一种基于altera公司的ipcore开发pci接口的设计方法,详细讨论了其系统结构和核心部分的内部功能模块,并完成了对板卡驱动程序的开发,同时给出了具体的仿真结果。
The voice and radar data in mdsl is an important testimony in the analysis of aero accident , so the reliability of recording and the synchronization of voice data and radar data reordered are the first requirement for the mdsl system . the system is a typical real time system 在事后航空事故分析中, “多通道数字同步记录仪”记录的语音和雷达数据是重要的依据,因此数据记录的可靠性和语音数据和雷达数据记录的严格的同步是该系统最重要的要求,该系统是典型的实时系统。
Aimed at the civil aviation airport , this warning system for air traffic control automation system includes amalgamation process of multi - radar data , warning process of flight conflict and low height , altogether with conflict display terminal . the theory and method about programming of all these units are told in detail in this article , and added to that is method of processing data with two networks and between two computers , master machine and slave one 在本文中,将对这个告警系统中的多雷达数据融合处理单元、飞行冲突和低高度告警处理单元,以及冲突显示终端的系统原理、软件实现的方法、功能等作具体的阐述。另外,还将讲述到整个空中交通管制自动化系统中双机、双网工作模式的实现。
