| Abstract | 地面动目标检测(GMTI)是天基分布式雷达的重要应用之一,采用多载频模式可有效减少孔径稀疏引起的动目标检测盲区,提高GMTI性能.针对多载频天基稀疏阵雷达的空时自适应处理(STAP)方法,基于多通道幅相误差模型,推导了多载频模式下存在幅相误差的杂波协方差矩阵表达式.通过仿真分析了幅相误差对多载频稀疏阵最优STAP方法的影响. |

TheM T I b lind zones cau sed by sparse array can be effect ively reduced by using multicarrier frequency so that GMTI performance can be improved.Based on the model of channel amp litude and phase errors for mult icarrierf requency space based sparse array, the clutter covariance mat rix exp ression w ith erro rsw as derived, and the impact of amp litude and phase errors on optimal STAP was invest igated th rough simu lat ion s. |
