Chirp scaling algorithm is considered more efficient and widely applicable when the bistatic SAR system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by Taylor expansion are so large that the algorithm could lose its precision.In such a case,an equivalent mono-static SAR range mode which has fewer errors than Taylor expansion with large squint angle is proposed to substitute the range history of bistatic SAR.Then bistatic SAR images with large squint angles are gotten by common Nonlinear CS algorithm.The effectivity of the method is verified by Matlab simulation.
在正侧视或小斜视情况下,CS算法具有较好的聚焦性能和广泛的适用性,但在斜视角较大的情况下,该算法将散焦而不能成像,因而提出了用等效的单基地距离模型来代替双基地距离历史的方法,解决了大斜视角情况下距离模型二阶近似误差较大的问题,并结合单基地非线性CS算法,实现了在大斜视角情况下的基于GPS反射信号的双基地SAR高精度成像,最后通过Matlab仿真进行了验证。

The result shows that the images of ALOS should be used in combination with the images of other satellites when we conduct large-scale, large-area, high-precision and short-cycle land use map updating and dynamic monitoring. This is because the images of ALOS have such shortages as large amounts of work and strict application.

The data of femur biodymamics showed that acupuncture and moxibustion could increase the biggest load, modulus of elasticity, the biggest flexibility. The data of shank bone morphometry showed that acupuncture and moxibustion could increase percentage of bone trabecula bulk, lessen percentage of bone trabecula absorption and restoration, slow the rate of bone trabecula mineralization. Slices indicated that the structure of bone trabecula became basically complete.

The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO-LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO-LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km . 4 The RAAN of TS and RS has a great influence on the LEO-LEO occultation number, but has little influence on occultation distribution.
结果指出:1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距;而这些参数对一年掩星事件的经度分布影响都不大;2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大,两卫星倾角接近互补时掩星事件最多,两颗LEO卫星中与90°相差较大的倾角决定了LEO-LEO掩星事件的纬度分布范围;3发射卫星和接收卫星处于同一轨道高度时,LEO-LEO掩星事件数取得极大值,发射卫星和接收卫星都采用600 km的轨道高度,一年LEO-LEO掩星事件数最多;4 发射卫星和接收卫星升交点赤经的相互关系对LEO-LEO掩星事件数量影响很大,发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多,RAAN对掩星事件纬度和经度分布影响不大;5近地点角距对掩星事件数量和分布影响都不大。

Now you know that I heart everything about you And that's why it's quite hard to get through this alone You're the only one I can talk to about it In my darkest night I will be on my own These walls that we climb are hard to recognize They fall when I say your name Here we go Fast and slow On the big chair But we don't know Where we're going On the big chair Don't you know it's hard, quite, in the time of confusion To tell you that I love you You see it could have been me instead of you It could have been me if I wanted to But it wasn't So we'll have to face the truth These walls that we climb are hard to recognize They fall when I say your name Here we go Fast and slow On the big chair But we don't know Where we're going On the big chair Time to pull the shutters down Breakin' clouds don't make a sound?

The thoracic duct endothelia in vitro could remain their biological properties, and could be made a tool for studing their functions and cancer metastasis mechanism by lymphatics. The positive expression of VEGF-C in cancer cells was correlated with cancer development, it seem to be that VEGF-C induce lymphoangiogenesis through its receptor Flt-4. The Flt-4 expression of lymphatics in cancer tissues was assosiated with cancer development, it is considered that there are new lymphatics in cancer tissues.
