摘要 机载雷达平台的空时自适应处理(Space-Time Adaptive Processing,STAP)通常用于对地面运动目标的检测,但无法实现对相应目标的空时参数估计。该文基于线性约束自适应单脉冲技术,提出一种运动目标空时参数估计新方法。该方法通过对差波束进行零点约束、鉴角率约束及去耦约束,有效地克服了主瓣内杂波对差波束形状的影响,保持了单脉冲特性,提高了目标空时参数的估计性能。仿真结果表明,与同类方法相比,该方法具有优异的空时参数估计性能。 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.
