我们提出了使用的正交基函数,特别是,shapplanar和扁长椭球波函数,在射电天文成像。通过使用这些方法,可以克服传统的基于像素的图像去卷积的一些局限性。因此,这些技术将使我们能够增加可实现的成像动态范围,从而为新的科学成果铺平道路。我们给出了这种方法的当前状态的概述,并提供其使用的例子。
We present the use of orthonormal basis functions, in particular, shapelets and prolate spheroidal wave functions, in radio astronomical imaging. By using such methods, it is possible to overcome some limitations of traditional pixel based image deconvolution. Therefore, such techniques will enable us to increase the achievable imaging dynamic range thus paving the way for novel scientific results. We give an overview of the current state of the art of such methods and provide examples of its use.
