A subspace-tracking approach to interference nulling for phased array-based radio telescopes.

A subspace-tracking approach to interference nulling for phased array-based radio telescopes.

Several next-generation radio telescopes, now in the planning stages, are based on phased-array technology. One reason for this is to make use of adaptive nulling techniques to combat radio frequency interference, which is a growing problem for radio astronomy. This paper presents a low-complexity a...
