Abstract : This paper presents the analysis of a signal processor that senses the phase front distortion across a monopulse antenna due to glint phenomena and rejects the consequent erroneous tracking data. The resulting glint reduction achieved by applying a combination of thresholds to the normalized sum channel signal and to the normalized imaginary component of the complex ratio D/S is presented. The results show that for a specified fraction of rejected data, maximum glint reduction is obtained by thresholding on sum channel information alone. (Author)
