Self-Triggering of Radio Signals from Cosmic Ray Air Showers

Absolutely calibrated measurements of the electric field strength (dual polarisation) with the LOPESSTAR detector were performed in coincidence with the well-established air shower detector KASCADE-Grande.This thesis discusses in detail the influence of background sources on the detector configuration as well as the resulting self-trigger system. The implemented trigger suppresses strong background signals from the industrial environment and is the basis for a hardware self-trigger.
