Abstract Technique of Space-Time Adaptive Processing (STAP), which is usually employed by airborne radar to detect the ground moving targets, can not estimate the spatial-temporal parameters of the corresponding targets. Based on the linearly constrained adaptive monopulse technique, a new method for estimating the spatial-temporal parameters of moving targets is proposed in this paper. The proposed method utilizes the beam null, monopulse slope, and decoupling constraints to remove the worse influence on the beam shape from the mainbeam clutter, keep the monopulse characteristic, increase the estimation performance of the spatial-temporal parameters of the moving target. Simulation results illustrate that the proposed method possesses the excellent estimation performance of the spatial-temporal parameters compared with the other similar methods.
