摘要
机载共形阵是机载有源相控阵天线发展的下一个目标。共形阵天线的阵元具有不同的方向性,空间分辨率算法必须考虑来波的极化问题。本文研究了空间信号波达方向(Direction of Arrival,DOA)估计算法的现状,分析了一种适用于共形阵天线空域自适应波束形成的高速滤波算法。
Airborne active phased array antenna is aiming at the techniques of airborne conformal array antenna.The polarization of coming wave must be considered when computing the spatial resolution because of different directions of conformal array antenna elements.The present situation of spatial signal Direction of Arrival（DOA） is studied in order to solve the polarization of coming wave.A high speed filtering algorithms which can be used to spatial adaptive beam forming in airborne conformal array antenna is analyzed to match the needs of real-time property.
