摘要: We propose an Omega-K algorithm for accurate SAR image reconstruction, taking into account the continuous movement of the antenna during transmission and reception of the signal.关键词: image reconstruction radar imaging synthetic aperture radar high resolution SAR image reconstruction omega-k ...
k-omega模型的优点：形式简单，易于理解。能够准确地体现壁面行为。与k-varepsilon模型相比，k-omega模型在处理近壁面流动行为时，不会引入非线性项。兼容层流和湍流过渡态建模。在原始Wilcox模型中，对自由流的边界设置非常敏感。k-omega模型的缺点：在处理近壁面流动行为时，会引入非线性项，从而导致计...
I've been using k-epsilon much in the past, but today I'm thinking about working with k-omega. I understand omega is a function of epsilon (i.e. omega is the specific dissipation rate), and the models may have some advantages over the k-epsilon models. Can anyone add some insight ...

For the FL-BSSAR imaging, we introduce a modified omega-k algorithm. Specifically, using rotation and shifting of the receiver path and resampling of the transmitter path, we convert the FL-BSSAR into the side-looking BSSAR. Then, we modify the matched filter and Stolt interpolation using ...

K-Omega模型中的"K"代表湍流动能,"Omega"代表旋转速度。这个模型通过建立湍流动能K和旋转速度Omega的传递方程来描述湍流的状态。在这些方程中,特定耗散率是一个关键的参数,它反映了湍流中能量耗散的快慢程度。 具体来说,特定耗散率是湍流动能和旋转速度的耗散率,它与湍流的特征长度尺度有关。这个特征长度尺度通常由流...
