WebSTAP radar processing is combining temporal and spatial filtering that can be used to both null jammers and detect slow-moving targets. It requires very high numerical processing rates, as well as low latency processing, with dynamic range requirements that generally require floating-point numerical representation. WebAn ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve [1] and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton.
