Performance analysis for angle measurement of monopulse radar with non-consistent amplitude-phase features

Monopulse radar is widely used for its high angle measurement and great anti-interference performance. In this paper, a classical signal processing method of sum and difference patterns for anti-symmetrical monopulse radar using digital beam forming (DBF) technique is proposed. Effects on angle measurement performance caused by amplitude-phase non-consistency are analyzed and its corresponding simulation results are verified. These results can be used in practical engineering implementation. Furthermore, the method proposed in this paper can also be applied in other tracking radar systems which include DBF.
