A chirp scaling algorithm for airborne bistatic sar is proposed , which is suitable for the flight configuration that transmitter and receiver follow parallel path with equal velocity in broadside looking mode . airborne bistatic sar echoed signal model of this particular flightpaths is derived . the model is converted into the range doppler space and is mapped from double range variables to single range variable domain 本文建立了這種特殊飛行模式下雙基地sar的回波信號模型,推導了它在距離多普勒域的表達式,解決了信號模型從雙距離變量域向單距離變量域轉化的問題,并推導了cs因子的線性近似表達式,分析了算法中各種近似造成的誤差。

The performance of the pbg antenna using the new pbg cover together with a pbg substrate is studied by the fdtd method together with the pml boundary treatment . the numerical results show that a more focused beam radiated in the broadside direction is achieved . the gain of the pbg patch antenna in the forward direction is improved by about 6 db . the radiation directivity is improved significantly and reaches 11 . 5 db , which is 0 . 4 db less than the maximum value that is allowed physically for this size of the antenna ( this difference is about 4 . 1 db less than the difference achieved by thevenot et al . , 用fdtd方法并結合pml吸收邊界條件,我們對加了這種新的覆層結構并且基底鉆孔的復合結構電磁(光子)晶體貼片天線的性能進行了研究,結果證明加了這種新的電磁晶體覆層結構以后,天線的波束收攏很多,并且向前輻射的增益大大提高,與普通天線相比,天線的e面和h面方向圖上向前輻射的增益均提高了約6db ,另外,該復合結構天線的方向性系數達到了11 . 5浙江大學博士學位論文db ,與該物理尺寸天線的方向性系數的理論極限值( 11 . 9db )相差0 . 4db ,該差值比thevenot等人設計的電磁晶體覆層天線的相應差值減少了約4 . 1db ,比qiu等人設計的電磁晶體天線的相應差值減少了約1

3 . after the parameters of the array structure are got , simulation software , such as cst microwave studio , cts design studio and ansoft hfss , are used to design the power dividers for the radiation units in the horizontally polarized direction of the array . these power dividers adopt structure of coupling slots in the narrow side of main rectangular waveguides , in which the narrow side of the main waveguide and the broadside of secondary waveguides are crossed at locations of each slot 3 .在得到滿足指標要求的陣列結構參數后,采用cstmicrowavestudio 、 ctsdesignstudio和ansofthfss等電磁仿真軟件對陣列在水平極化方向的行饋功分器進行仿真設計,該陣列的行饋功分器采用波導窄邊單縫耦合饋電結構。

About three in the afternoon he came up with us , and bringing to by mistake , just athwart our quarter , instead of athwart our stern , as he intended , we brought 8 of our guns to bear on that side , and pour d in a broadside upon him , which made him sheer off again , after returning our fire , and pouring in also his small shot from near 200 men which he had on board 他們本想攻擊我們的船尾,結果卻橫沖到我們的后舷。我們把八門炮搬到了這一邊,一起向他們開火。海盜船邊后退,邊還擊他們船上二百來人一起用槍向我們射擊。

Based on these studies , the properties of doppler and resolutions are analyzed . because the imaging algorithm of bistatic sar is related to the geometry models , the dissertation gives particularly empathies on the parallel model and the static receiver model in the broadside side - looking and stripmap 本文首先建立了任意飛行模式下雙基地sar的幾何模型和回波模型,分析了其多普勒特性和分辨率特性,得出雙基地sar成像算法與飛行模式有密切關系的結論。

Besides , it ’ s also very convenient to add many kinds of phase errors required by the phase error compensation and sar image processing research farther . for imaging algorithms , range - doppler algorithm is extended to broadside stripmap airborne bistatic sar successfully 另外,在我們方法的流程中可以方便地加入載機運動參數誤差、天線波束指向誤差及頻率源的穩定性等各種相位誤差,也為今后進一步研究相位誤差補償及圖像處理等技術打下了良好的基礎。

In the last , the chapter proposes a new wide band imaging algorithm . the maximum bandwidth of the algorithm is larger for broadside looking or small imaging angle . at same time , interpolation is not needed for the algorithm , therefore the computation efficiency is high 本章最后還提出了一種新的寬帶成像方法,這種方法在正側視或較小成像角時可采用較大的信號帶寬,同時不用插值計算,因而有較好的運算效率,為寬帶成像提供了新的選擇。

She turned in every direction but the one i was bound to go ; the most part of the time we were broadside on , and i am very sure i never should have made the ship at all but for the tide 我當然不知道它的脾氣。它能轉向任何一個方向,就是不肯走我要去的方向,我大部分時間坐在船的內側,要不是有潮水幫助,我相信我這輩子也無法靠近大船。

Round she came , till she was broadside on to me - round still till she had covered a half , and then two - thirds , and then three - quarters of the distance that separated us 伊斯班裊拉號掉轉船頭,把它的一面船身靠近我,直到把小艇和大船的距離縮短為一半三分之一四分之一。

2 . the rd imaging algorithm of bistatic sar , which works on classical 2 - order range model especially on the parallel model in broadside side - looking and stripmap , is discussed . 3 2 .通過對sar成像原理和rd算法的研究,推導得出了基于平飛正側視模式( ct )下的rd算法。

That holds generally true even when the fire is delivered broadside against a body of infantry ( or a column of vehicles ) offering a fairly substantial target 這通常是正確的,大群的步兵或者一個車隊通常是一個相當合適的目標。

No , not i , said silver . flint was cap n ; i was quartermaster , along of my timber leg . the same broadside i lost my leg , old pew lost his deadlights “不,不是我, ”西爾弗說, “弗林特是船長我因為有這根木腿,只是管掌舵。
