为了检测单脉冲雷达接收通信的幅，相一致性，需要在天线上设置ＢＩＴ（机内检测）通道，空馈单脉冲天线在设置ＢＩＴ通道时全遇到一定的困难，本文介绍了一种要以圆满地解决问题的方法，它对于空馈相控阵天线尤其简便，已在实际天线系统中得到了良好的应用。

BIT channel must be set in monopulse radar for testing amplitude and phase in receiving channel.there are some difficulties for setting BIT channel in space-fed antennas.In this paper, a way is introduced for setting BIT channel in space-fed monopulse phased antennas to solve the problems.It is especially convenient for space-fed phased array antennas and it has been well applied to the antenna system.
