调整极坐标图像的大小

我有一个来自气象雷达的图像，该图像处于极坐标（方位角，范围）内。
正常的调整大小功能无法正常工作，因为它们假定图像以笛卡尔坐标表示。从scikit-image等中获取。

I have an image from weather radar which is in polar coordinates (azimuth, range). Normal resizing functions are not working as they presume the image in Cartesian coordinate I guess. From scikit-image etc.

我如何有效地调整图像的大小，并保持与笛卡尔相同的比例和特征。还是唯一的方法是转换为笛卡尔后再返回？

How can I resize the image effectively having same ratio and characteristics maintained as we get in Cartesian. Or the only way is to convert to Cartesian and then back ?

使用天气库显示的原始（掩码数组）：

Original (masked array) displayed using weather lib:

基于极坐标的轮廓：

调整数组大小（并使用imshow绘制）

resized the array (and plotted using imshow)

调整第三张图的效果很好，但我需要调整第一极坐标的大小。

Resizing the third graph works well but I need resized version of the first polar coordinates.
