现在的雷达都是在多脉冲观测的基础上进行检
测的,多个脉冲积累后可以有效地提高信噪比,从
而改善雷达的检测能力。积累处理可以在包络检波
前完成,称为检波前积累或者中频积累。信号在中
频积累时要求信号间有严格的相位关系,也就是说
信号是相参的,所以也称为相参积累。此外,积累
过程可以在包络检波后完成,称为检波后积累或者
视频积累。由于信号在包络检波后失去了相位信息
而只保留了幅度信息,所以检波后积累处理就不需
要信号间有严格的相位关系,因此这种积累又称为
非相参积累。实现非相参积累的方法有很多,例如
抽头延迟线积累(FIR 积累)器和反馈积累器。

说明: 波束图定义为当阵列输入为平面波时,阵列输出与平面波入射角的关系。阵列天线的方向图是全方向的,但阵列的输出经过加权求和后,却可以使阵列接受的方向增益聚集在一个方向上,相当于形成一个波束,(The wave beam chart defines to work as when array input for plane wave, array output and plane wave incidence angle relations. Array antennas s directional diagram is entire direction, but array output after weighting summation, actually may cause the directive gain which the array accepts to gather in a direction, is equal in forms wave beam, )
