Abstract
Cyclic MUSIC has been proposed as a direction finding technique that reduces the effects of noise and interference by exploiting the cyclostationarity of the signal of interest. The authors introduce two techniques for reducing the sensitivity of cyclic MUSIC to error in cycle frequency knowledge. Both techniques are shown to perform significantly better than conventional cyclic MUSIC when the cycle frequencies are not known precisely
