Abstract

In the radio observation based on the large single antenna, in order to reduce the interference of navigation signal L2 from observation of the red-shifted HI spectral line at L-band, we used the an auxiliary channel and normalized LMS algorithm, and proposed new evaluating indicators deduced by theoretical method. Finally, we verified the suppression performance and the indicators’ utility by multiple simulations and statistical method.
