ABSTRACT:
Improved performance in electronic countermeasure systems that utilize main lobe shifting techniques to jam track while scan threat radars are achieved through the use of a modulation sweep program that overcomes scan rate frequency and phase uncertainties. The modulation sweep program is used in conjunction with a conventional swept repeater modulation program. The modulation sweep program is disabled and the swept repeater modulation program is enabled when constant illumination sources or track while scan saturation conditions are encountered.
