摘要：

We here compare estimators of the mean radar reflectivity on images with different spectral properties. By working on complex data rather than detected images, we can take the speckle correlation into an count and thus obtain more accurate estimates. A robust and computationally efficient approximation of the optimal estimator is proposed.
