At last, a yield mapping system must have a data recording system 產(chǎn)量和位置信息最終要上傳到pc機(jī)存儲(chǔ)起來(lái),所以還要設(shè)計(jì)一個(gè)產(chǎn)量記錄系統(tǒng)。
Sar develops rapidly in recent years, the data acquisition and storing system, as the important part of sar system, was requested the more and more high working performance . some data recording system cannot suit the higher requirement any more 近年來(lái)隨著合成孔徑雷達(dá)的高速發(fā)展,對(duì)作為其重要部分的數(shù)據(jù)采集和存儲(chǔ)系統(tǒng)提出了越來(lái)越高的要求,現(xiàn)有的一些數(shù)據(jù)記錄器已漸漸無(wú)法滿(mǎn)足sar系統(tǒng)對(duì)高速數(shù)據(jù)采集和存儲(chǔ)提出的要求。
In this research, the steady and temporal properties of two waves mixing ( twm ) were studied in a ce : knsbn crystal with a he-ne laser and a synchronous data recording system, and the process of twm was analyzed under a bump beam chopped condition 本文以he-ne激光為光源,采用實(shí)時(shí)光探測(cè)數(shù)據(jù)采集處理系統(tǒng),系統(tǒng)的研究了ce:knsbn晶體的兩波耦合穩(wěn)態(tài)特性及兩波耦合過(guò)程中信號(hào)光、泵浦光和光扇的時(shí)間演化,同時(shí)對(duì)泵浦光斬波兩波耦合過(guò)程進(jìn)行了分析。
In order to receive the data correctly and store it in computer for analysis and process, a kind of space tracking data recording system based on pci bus is designed and realized in this dissertation, which enhance the space tracking system ’ s integrality 本課題正是在這種應(yīng)用背景下,通過(guò)設(shè)計(jì)基于pci總線(xiàn)的數(shù)據(jù)錄取系統(tǒng),對(duì)航天測(cè)控系統(tǒng)地面站綜合基帶設(shè)備數(shù)字接收機(jī)所接收的中頻采樣信號(hào)和解調(diào)后的數(shù)據(jù)進(jìn)行接收和存儲(chǔ),將其送到監(jiān)控計(jì)算機(jī)中進(jìn)行調(diào)制方案驗(yàn)證和數(shù)據(jù)分析,從而進(jìn)一步完善了航天測(cè)控系統(tǒng)的設(shè)計(jì)。
