由於衛星散射計探視雷達回波的各向異性的雙調和性質,同時由於散射物理模型函數的非線性及信號中存在噪聲,使得常規點方式風場反演中風向有多至4個解的多解存在。It is blue in color, owing to the scattering of blue light by methane
由於大氣中的甲烷散射光線,天王星發出蔚藍的顏色。Thus, blue light cannot travel very far without changing direction in the atmosphere. red light, in contrast, can travel much farther. during sunset, we see a red sun because the red light can go directly to us and almost all the blue light is scattered away
地球的大氣擾動令星光閃爍不定,它更會散射光線,由於藍光比紅光更容易被大氣所散射,所以藍光在大氣中不能及遠,而紅光則基本上暢通無阻,結果在黃昏時,只有紅光能直達地面,而藍光則被大氣散射得七零八落,出現了令無數情侶陶醉的紅日倚山的美景。Scientists believe that many nearby galaxies harbour intermediate - mass black holes as very luminous x - ray sources, also known as ultraluminous x - ray sources. unlike supermassive black hole in the centre of a galaxy, these ultraluminous x - ray sources usually locate at the galactic disks
科學家相信,中型黑洞匿藏在許多我們鄰近的星系中,向四周發射超強射線,與超重黑洞不同的是,它們並非位於星系中心,而是散布在銀盤上。The micro - satellites cooperate together to accomplish one or more tasks, which has equivalent function with a big satellite. the new model system can provide more baseline and contribute to data fusion. it has much more advantage than conventional single spaceborne sar system because its baseline selection is agile and alterable
由於採用多星協同工作,該系統在保持高解析度情況下可實現寬測繪帶成像、動目標檢測以及地面高程測量等多項任務,並且這種分散式衛星能提供靈活多變的基線組合,可提升系統性能和擴展系統功能,同時提高衛星生存能力、實施規模生產和降低發射費用,具有傳統星載sar無法比擬的優勢。分享友人
