The theory and practice of infrared radiation surveying technology of geological structure in pit 礦井地質(zhì)構(gòu)造紅外探測(cè)的理論與實(shí)踐
Millimeter wave system has many distinct advantages such as miniaturizing system components , increasing frequency band width , providing higher detectability , uneasily influenced by atmosphere conditions , etc . this makes millimeter wave technique get the increasingly extensive application in radar , communications , electronic warfare , guidance , remote sensing , radiation survey , therefore the research of millimeter system is very vital for civil , the industry , national defense 毫米波系統(tǒng)具有可以使元部件小型化、增加系統(tǒng)帶寬、提供高分辨率以及受大氣條件的影響較小等許多明顯的優(yōu)點(diǎn),這使得毫米波技術(shù)在雷達(dá)、通信、對(duì)抗、制導(dǎo)、遙感和輻射測(cè)量等技術(shù)領(lǐng)域中得到日益廣泛的應(yīng)用,所以毫米波系統(tǒng)的研究對(duì)于民用、工業(yè)、國(guó)防具有重要的意義。
According to topographical control survey characteristics in the small towns of mountainous area , the paper presents two methods of control measure , namely , detailed survey and radiation survey , and makes some discussions from the precision , so as to solve some practical operation problems and improve the progress and precision measured 摘要根據(jù)山區(qū)小城鎮(zhèn)的地形控制測(cè)量特點(diǎn),提出“邊碎部邊控制”和“輻射點(diǎn)法”兩種控制測(cè)量方法,并從精度方面作一些探討,從而解決一些實(shí)際操作問題,提高測(cè)量的進(jìn)度和精度。
