不聚焦

a system of along-track mode sar based on the gps is established.by seeing the gps signal as a chirp,chirp scaling algorithm of this mode with large squint angle is investigated.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.

摘 要：建立了基于gps的顺轨sar系统模型，通过将gps信号等效为chirp信号，研究了在该模式下的大斜视角chirp scaling算法。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。

A recent television appearance on Jimmy Kimmel Live! focused more on housework than the prospect of Bryant refusing to report to training camp.

kobe最近参加了Jimmy Kimmel 的电台脱口秀，而访谈中更多的其实都是聚焦在有关kobe宁愿做家务也不出席在训练营中的问题。

Instead, you become susceptible to committing all the typical trading errors (hesitating, jumping the gun, not predefining your risk, defining your risk but refusing to take the loss and letting the trade turn into a bigger loser, getting out of a winning trade too soon, not taking any profits out of a winning trade, letting a winning trade turn into a loser, moving a stop closer to your entry point, getting stopped out and watching the market trade back in your favor, or trading too large a position in relationship to your equity).

相反，你容易犯典型的交易错误（犹豫，提前行动，不提前衡量风险，拒绝止损，大亏，提前兑现利润，赢利时没有兑现利润，让赢利变成了亏损，止损离进场点太近，被止损了，然后市场远离你而去，仓位太大）。5个基本的事实会让你的期望保持中性，思想聚焦于&现在的机会流&，因此，让你不再犯错了。

You do not want to control or limit conditions or possibilities, because you understand that this Universe, in which you and we are all focused, is vibrationally based and is managed by Law of Attraction.

你之所以不想去控制或限制环境以及可能发生的事情，是因为你明白，这个我们和你们共同聚焦着的宇宙，它的本质是能量振动，宇宙中的一切事物运行的规则是吸引定律。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
