Zusammenfassung

Ein Empfänger für die passive Mikrowellenradiometrie muß in der Lage sein, extrem kleine Signalleistungen nachzuweisen. Bei einer technisch festgelegten Empfangsbandbreite kann man aufgrund von Gleichung (1–33) auch sagen, daß der Empfänger möglichst kleine Änderungen der Antennentemperatur nachweisen können sollte. Das heißt, man kann die Grenzempfindlichkeit eines Empfängers durch die kleinste gerade noch nachweisbare Temperaturänderung der Antennentemperatur charakterisieren.
