Abstract :
EarthCARE (Earth Clouds, Aerosols and Radiation Explorer) is the 6th Earth Explorer Core Mission of the European Space Agency and a joint undertaking with the Japan Aerospace Exploration Agency (JAXA). It will study and analyze the interaction and impact of clouds and aerosols on the Earth´s radiative budget. Along with other instruments, the satellite payload will include a 94 GHz Cloud Profiling Radar (CPR) with Doppler capability. This paper presents the development of a High Power Amplifier for the EarthCARE CPR and reviews HPA requirements, design and performance.
