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。

如果在您的软件中需要输出报表,您也许有很多办法,但实现起来估计就不简单了。其实用DHTML提供的表格可以在很大程度上满足一般的需求。本文正是试图通过包装对DHTML表格的操作使程序员从无聊的报表设计中解脱出来。-If you need software output statements, you may have many alternatives, but will not be realized simply estimates. Actually, using DHTML forms can be provided in large measure to satisfy demand. This paper is an attempt to right through the packaging DHTML forms so that the operation of programmers from the tedium of the statements designed to extricate themselves.
