摘　　要：接收波束形成的关键技术之一是接收校正,校正精度直接影响形成波束的副瓣电平,文章详细介绍校正的原理、方法及相关参数的取得。用试验数据取得的相关校正参数,对测试信号扫描形成垂直波瓣,其副瓣电平低于设计的39dB,说明该校正方法获得了满意的校正结果。Receiving correction is one of the key technologies for receiving digital beam forming （DBF） ; correcting precision directly affects level of sidelobe which forms beam. Principle of correction, correcting method and related parameters are introduced in detail. By using of correcting parameters obtained from experimental data, vertical lobe is formed through scanning test signal, level of sidelobe is less than 39dB, which shows that perfect correcting result can be achieve with the correcting method.
