| 摘 要： | 为了满足实际阵列天线处理要求和提高经典局域联合处理(JDL)STAP算法的稳健性,提出了一种基于信号表示过完备理论的改进JDL-STAP算法。该方法利用包含所有感兴趣观测角度形成的过完备基集合构造从空-时域到角度-多普勒域的变换矩阵,将空时数据精确映射到局域处理区域的角度-多普勒单元,再在低维空间内进行空时二维自适应处理。仿真结果表明:改进JDL算法比经典的DFT-JDL算法具有更优的性能和稳健性。

| Abstract: | In order to meet the requirements of physical array antenna processing and improve the robust of classical Joint-Domain Localized(JDL) STAP algo-rithms,the paper proposes a modified JDL-STAP algorithm based on the signal representation theory using overcomplete bases.The method first formulates the transforming matrix by employing an overcomplete basis set represented by all in-tended testing angles,then the space-time data are mapped into the angle-Doppler bins of localized processing region accurately,and... |
