Abstract

The monopulse angle measuring technique is widely adopted in radar systems due to its simplicity and speed in accurately acquiring a target angle. However, in a spatial adaptive array, the beam distortion incurred by adaptive beamforming, can result in severe performance deterioration. A novel constrained monopulse angle measuring algorithm is proposed in this paper for spatial adaptive arrays. This algorithm is able to suppress the interference without suffering from beam distortion. Compared with previous constrained algorithms, the proposed algorithm adopts a new form of constraint in forming the difference beam with the merit that it is more robust in most practical situations. At the same time it also exhibits the simplicity of traditional monopulse, helping to make this algorithm even more appealing to use in adaptive arrays. In addition, the theoretical mean and variance of the monopulse estimator is derived for theoretical analysis. Mathematical simulations are formulated to demonstrate the effectiveness and advantages of the proposed algorithm.
