Nearly the entire system was developed in the Laboratorio di Geofisica Ambientale at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Rome. It exploits advanced techniques for signal analysis, recent technological devices and PC resources. This paper describes design concepts and performance of the new ionosonde. %K ionosonde %K pulse compression %K phase coherent integration %U http://www.annalsofgeophysics.eu/index.php/annals/article/view/4377
