sawtooth modulated jamming

sawtooth modulated jamming

[′sȯ‚tüth ¦mäj·ə‚lād·əd ′jam·iŋ]
(electronics)
Electronic countermeasure technique when a high-level jamming signal is transmitted, thus causing large automatic gain control voltages to be developed at the radar receiver that, in turn, cause target pip and receiver noise to completely disappear.
