说明： 中频验波是对信号进行中频直接采样和数字正交处理后,产生的I 支路和Q 支路信号序列在时间上会错开一个采样间隔,需要进行定序处理,恢复成同步输出的I、Q 两路信号序列。现代雷达普遍采用相参信号处理,而如何获得高精度基带数字正交( I , Q) 信号是整个系统信号处理成败的关键,以前通常的做法是采用模拟相位检波器得到I、Q信号,其正交性能一般为:幅度平衡在2 ％ 左右, 相位正交误差在2°左右,即幅相误差引入的镜像功率在- 34dB 左右。这限制了信号处理器性能的提高, 为此, 近年来提出了对低中频直接采样恢复I、Q 信号的数字相位检波器。随着高位、高速A/ D 的研制成功和普遍应用,使得数字相位检波方法的实现成为可能。
