“…All these methods have been extended to the space-time case. This has been presented in [ 19 , 20 , 21 ]. However, all these methods require calculation of first or second derivatives of array manifold with respect to angles of arrival, which makes these methods more sensitive to the error of array elements distribution.…”

The monopulse angle measuring technique is widely adopted in radar systems due to its simplicity and speed in accurately acquiring a target’s angle. However, in a spatial adaptive array, beam distortion, due to adaptive beamforming, can result in serious deterioration of monopulse performance. In this paper, a novel constrained monopulse angle measuring algorithm is proposed for spatial adaptive arrays. This algorithm maintains the ability to suppress the unwanted signals without suffering from beam distortion. Compared with conventional adaptive monopulse methods, 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 one-dimension monopulse, helping to make this algorithm even more appealing to use in adaptive planar arrays. The theoretical mean and variance of the proposed monopulse estimator is derived for theoretical analysis. Mathematical simulations are formulated to demonstrate the effectiveness and advantages of the proposed algorithm. Both theoretical analysis and simulation results show that the proposed algorithm can outperform the conventional adaptive monopulse methods in the presence of severe interference near the mainlobe.

“…However, the number of secondary sample data available from a non‐stationary environment is often insufficient. This is especially true in non‐homogeneous environment because the available amount of secondary sample data which have the same statistical characteristics with the clutter in the primary cell is very limited [28–30].…”

“…However, the performance of classical monopulse lost severely after employing STAP [5]. Various methods were proposed to improve the accuracy of space-time adaptive monopulse [6][7][8][9]. A simple and practicable one is Constraint-Based Space-Time Adaptive Monopulse (C-STAM) taken by Fante [10] where several constraints are introduced to form an undistorted monopulse pattern.…”

The principle and cost analysis of Constraint-Based Space-Time Adaptive Monopulse (C-STAM) are given. Based on the idea of cognitive radar, a novel Knowledge-Aided Constraint-Based Space-Time Adaptive Monopulse (KA-C-STAM) is proposed. With the knowledge given by a tracking filter in data processing, the KA-C-STAM improves the performance of angle estimation. Numerical examples verify the validity of the novel method.
