已经成功地研究出一种简单而有效地处理多射射频信息的方法。这种方法是通过单个射频调谐器传输多路信号,然后在中频复现各个信号分量。这种新型WJ-1988幅度单脉冲定向处理器使单个宽带调谐器能同时处理多个天线的定向输出,而不会引起不希望有的干涉仪效应。该设备包括一个安装在天线附近的有源多路调制器、一个定向处理器单元和一个控制显示单元。
We have successfully developed a simple and effective way to process multiple RF information. This method transmits multiple signals through a single RF tuner and then reproduces the individual signal components at the IF. The new WJ-1988 amplitude single pulse directional processor enables a single wideband tuner to handle directional outputs from multiple antennas simultaneously without causing unwanted interferometer effects. The device includes an active multiplexer mounted near the antenna, a directional processor unit and a control display unit.
