This paper analyses the applied characteristic of phase - locked loops ( pll ) for the forward motion compensation technology of lmk aerial survey camera . according to the analysis , a new style pcb is produced . the realization by software for the forward motion compensation is discussed in this paper , which is realized by the ti prduction tms320f240 在對lmk航空攝影機像移補償控制系統的再設計工作中,本人設計出了新的補償電路線路板,并進行了幾項典型的實驗研究和前向運動補償效果評價,經過外場飛行試驗,進一步證明了該設計的可靠性、可行性、實用性。

2 . combined , spatial and quantity structure of the land use according to baoying county ' s 2001 aerial survey data , the author adopts a series of indexes for analysis . the results indicate that cultivated land is the main land use type in this area and its space distribution is more centralized 寶應縣土地利用的數量、空間和組合結構根據江蘇省寶應縣2001年航測編繪的土地利用現狀圖,采用一系列指標進行分析,結果表明,寶應縣的主要用地類型為耕地,其空間分布比較集中,在整個區域內占主導地位。

Domestic services are operated for a variety of purposes such as sightseeing , aerial survey , filmingphotography , and maintenanceconstruction work , etc . in 2001 , a total of 4 , 363 domestic flights were operated , averaging about 12 per day . as regards helicopter services between hong kong and macao , 18 , 382 flights with a passenger throughput of 107 , 696 were recorded , representing increases of 5 . 4 per cent and 14 per cent respectively when compared with 2000 在二零零一年,香港共營辦4364架次本地直升機航班,平均每日約為12架次;至于往返港澳兩地的直升機航班,則有18382架次,載客量為107696人次;與二零零零年比較,航班架次和載客量分別上升5

We could have it as the foundation for the aerial survey camera redesign . the performance of the collectivity is analysed finally , the effect of forward motion compensation is estimated . the equivalent residual image motion of the compensation control system is very small 最后,本人利用tms320f240dsp處理器的部分資源,對前向運動補償控制系統的軟件實現方法進行了研究和探討,取得了較為滿意的控制效果,為今后航空攝影機電控系統的設計工作打下了基礎。

The region , then home to about 300 , 000 elephants , now only has about 10 , 000 . most recently , during an aerial survey made from aug . 3 to aug . 11 , mike fay , a wildlife conservation society conservationist and national geographic explorer - in - residence found five elephant massacre sites 最近,在8月3日至11日期間進行的一項空中勘測中,國際野生生物保護學會的成員同時也是美國國家地理協會駐當地專家的邁克費伊發現了5處大象屠殺點。
