A generalized likelihood ratio test is used to find approximate limits on the angular resolution of two targets for a mechanically rotated antenna. The accuracy of maximum-likelihood azimuth estimates of the two interfering targets is also investigated. The results are found to be comparable to those obtained by directly processing the outputs of the individual elements of an antenna array. A simple ad hoc procedure for angular resolution and estimation is also analyzed. The performance of the ad hoc test is found to be within 2 to 3 dB of that of the generalized likelihood ratio test.
