| 摘 要： | STAP（时空自适应处理）已被证明是机载雷达在强杂波环境下检测目标的一种有效方法。文中对面阵和线阵作比较，分析了阵元幅相误差对线阵中二维STAP（2D-STAP）性能的影响，对面阵天线采用的三维STAP（3D-STAP）技术，补偿因存在阵元幅相误差而导致各列子阵俯仰方向图的不一致性。对仿真数据处理结果证明三维处理具有更好的性能和很强的误差容错能力。

| Abstract: | Space-time adaptive processing（STAP） has been proved to be a effective method to detect target in superclutter environment for airborne radar, comparison of planer array and linear array, the impact of element amplitude and phase errors on the two dimension space-time adaptive processor＇s （STAP） performance in linear array is analyzed. A three dimension space-time adaptive processor is introduced to planer array, which is aimed at compensating the discrepancy of column subarray pitching patterns resulting from the amplitude and phase errors. It is verified by numerical simulations that 3-D processor has a better performance and a perfect tolerant ability to errors. |
