non-uniform speed
解釋
非均勻速率-
Uniform linear motion blurring is also a common kind of blurring in motion, because motion of changed speed and non - linear can be regarded as composed result of uniform linear motion
勻速直線運動模糊亦是動態情況下的一種典型模糊，因為變速的、非直線的運動在某些條件下可以看成是均勻的、直線運動的合成結果。 -
Several key techniques of carving and milling machine cnc system are deeply studied they include : the transformation, data rebuild and interface design of huge volume nc program produced by cam ; the algorithm of cubic parametric spline pre _ interpolation and high speed real time interpolation in the cnc system, which. will gain a much higher surface precision and cutting speed ; methodology and algorithm of movement velocity acceleration control on a real time forecast _ and _ prejudge basis is designed. therefore, a smooth movement is insured. the shake and noise problem caused by non _ uniform pules for driving stepping or servo motor is solved by an improving algorithm to generate uniform pules

Actually, the initial use of emd algorithm is not in radar field, which is derived and utilized initially on the ocean or earthquake wave analysis. firstly, the emd algorithm adapted for the radar signal is examined in the dissertation. secondly, resolution improving in sar and multi - targets with non - uniform speed imaging in isar is studied by using emd algorithm the main work of the dissertation is as following : a ) by analyzed the emd decomposing results before and after matching filtering, the right position of emd decomposition in the imaging process is determined
由於emd演算法一開始並不是在雷達領域發展的，文獻中已有的演算法主要是針對海波、地震波等，所以本文首先分析了適用於雷達信號的emd演算法，並從sar和isar回波信號的特點出發，以emd演算法分解后的雷達信號為基礎，針對目前sar成像中的高分辨問題、 isar中非勻速和多目標成像清晰度不高等問題，研究了emd演算法在sar與isar成像處理中的應用，並採用大量模擬試驗對研究成果進行了驗證。 -
Because the internal structure of high - speed long - range flying objects ( hslrfo ) is so complicated and the mass distribution is extremely non - uniform, the precision of the mass characteristic parameters obtained from theoretical calculation is not enough to be applied to the practical measurement and control. the special test system for the mass characteristic parameters of high - speed long - range flying objects, therefore, is in great need and it is also necessary to study its performance
由於高速遠程飛行物體的內部結構非常復雜，質量分佈不均勻，在科學研究過程中進行的理論計算得到的質量特性參數與其使用要求相差甚遠，基本不能作為計算和測控參數使用，因此必須研製專用的測量系統，並對測量系統的測量特性進行研究。
