We consider the continuous wavelet transform Phi(h) associated with the spherical mean operator. We investigate the localization operators for Phi(h), in particular, we prove that they are in the Schatten-von Neumann class. Next, we analyze the concentration of this transform on sets of finite measure. In particular, Donoho-Stark and Benedicks-type uncertainty principles are given. Finally, we prove many versions of quantitative uncertainty principles for Phi(h).
