Impulsive noise rejection in HF radar using a linear prediction technique

Abstract

The performance of an HF Doppler radar is degraded by signal corruption due to impulsive interferers such as atmospherics and meteor train echoes. These interferers raise the Doppler spectrum background noise level, thereby reducing target to noise power ratios. In this paper, we make modifications to a known linear prediction missing data technique, and show that this technique is effective against HF radar impulsive interference.
