Abstract :
This paper presents the design of two spaceborne Doppler radar for 3D winds mapping inside cloud at 94 GHz : first one corresponds to radar with high quality of the retrieved 3D components of the wind field without scanning capability (fixed antenna with two reflectors) ; second one corresponds to scanning Doppler radar with swath width capability thanks to conical scanning antenna (rotation of all the instrument).
