【摘要】 针对和差波束法系统自由度极低、难以适应实际电子战环境的特点,本文研究了一种改进的和差波束时域滑窗空时自适应处理(STAP)方法的杂波抑制机理,并与和差波束相邻多普勒通道STAP方法进行了性能比较与分析。理论分析与计算机模拟实验表明,在非均匀杂波环境下,该方法具有更强的杂波与干扰抑制能力和误差鲁棒性,具有较好的应用前景。更多还原

【Abstract】 The system degrees of freedom of Σ△-STAP method is so low that it is not suitable for modern electronic warfare environment.The clutter suppression principle of an improved practical Σ△-STAP approach with time-delay taps is studied in this paper.Theoretical analysis and computer simulation illustrates that this method has better performance and error robustness than that of the adjacent Doppler channel ∑△-STAP method,which is very suitable for the nonhomogeneous clutter environments and has good application potential.更多还原
