从动目标模拟器要求的分析可看出,需要有一种反射型单边带调制器良好地抑制全部不需要的边带,但不抑制载波。动目标模拟器载波不需抑制的原因是:来自调制器的反射载波在本振频率上,只是在混频器中稍微地改变了本振功率。无边带的反射载波对混频器输出没有影响。(但应注意,双通道
Analysis of the requirements of the slant target simulator shows that a reflective single-sideband modulator is needed that well suppresses all unwanted sidebands but does not inhibit the carrier. The reason that the moving target simulator carrier does not need to be suppressed is that the reflected carrier from the modulator at the local oscillator frequency only slightly changes the local oscillator power in the mixer. The bandpass reflected carrier has no effect on the mixer output. (But note that dual channel
