Abstract
The device, a microwave pulse signal amplifier, includes an input (E), designed to be connected to a wideband reception head (A, H) suitable for picking up pulse emissions, on which continuous emissions can be superposed, a detection stage (1), connected to this input (E), and providing a rectified signal (SP1), and means for processing (2) the rectified signal (SP1) to establish a rectified pulse signal (SP4), rid of at least part of the effects of possible continuous emissions. The level of the continuous emissions is evaluated by a feedback loop (20, 21) activated (22) when there are no pulse emissions, and is subtracted from the level of the rectified signal (SP1).
