摘　　要：讨论了定向发射、全向接收体制稀布阵综合脉冲孔径雷达系统发射天线阵的设计及工程实现。研制了以八木天线为单元的八元发射天线阵。实现了天线单元的小型化;根据稀布阵理论对天线布阵的要求,从工程实用角度出发,指出了天线单元之间距离的选取准则,为发射天线阵的工程实施提供了可靠的理论依据。The design and engineering realization of the transmitting antenna array used for sparse-array synthetic impulse and aperture radar system in omnidirectional transmitting and directional receiving manual is discussed. The transmitting array of eight Yagi-uda antenna elements with small size is proposed. The choice rule of distance between array element is presented for the requirements of sparse-array theory from the view of engineering application. The available foundation is paid for the engineering practice of the transmitting antenna array of the SIAR system.
