ABSTRACT:
A noise test set for analyzing the presence of phase noise in a radar signal. A delay line discriminator using a fiber optic cable and laser light modulated by the radar signal are used. Both direct and indirect modulation techniques are disclosed, together with techniques for generating and injecting a calibration signal.
