我的朋友给我这个。我希望这对其他人有帮助。

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。 ()
