Operating in bad environments and wide band conditions, the amplitude and phase of monopulse sum and difference channels may drift severely.
工作在宽频及恶劣环境条件下的单脉冲雷达，和差通道的幅度和相位会发生严重漂移。

To design and manufacture a constant-source with adjustable amplitude value and the test system, and to realize the examination of zener diode voltage drift parameter, is very important.
设计制作出一个幅值可调的恒流源及其测试系统，实现稳压二极管电压漂移参数的检测，至关重要。
