针对可扩展孔径阵方位估计误差在工程使用中受装载平台影响大的问题，开展建模仿真与实验研究。基于一种装载于移动无人平台的双层圆柱形孔径可扩展的多元线列阵开展建模，根据实际使用的场景和安装平台，设计了具备时延补偿功能的波束形成算法和自适应姿态补偿算法。通过仿真分析和实验验证， 证明该方法可有效减小该种可扩展孔径阵的方位估计误差，并且具有较好的稳定性。
In response to the problem that azimuth estimation error of the expandable aperture array is greatly affected by loading platform，modeling and simulation and experimental study have been carried out. Modeling of the expandable aperture is based on a double-layer cylindrical multi-element linear array，and the expandable aperture is installed on unmanned platforms. According to the actual use scenario and installation platform，a beam forming algorithm with delay compensation function and self-adaptation attitude compensation algorithm are designed. Simulation and experimental results show that the proposed algorithms can effectively reduce the azimuth estimation error of this extensible aperture array and have good stability.
