Advances in the associated electronics have lowered the cost and reduced the size of the instruments. These electrons are accelerated by a positive electrostatic field and fall upon a metal surface where they emit secondary electrons that are again accelerated to generate more electrons at the next metal surface. The development of radar for detecting and tracking aircraft led to the simultaneous need for wideband electronic-noise sources as radar jammers.
