#CMT# #/CMT# The device has an ellipsoidal reflector (RE1) reflecting spherical microwaves radiated by microwave radiation sources (C1 - C3), where the sources are placed in neighborhood of a focus (FA1) of a reflector (RE1). A plane reflector (RP) contains a focus (FB1) of the reflector (RE1) for reflecting microwaves reflected by the reflector (RE1). An ellipsoidal reflector (RE2) has a focus (FA2) merged with the focus (FB1) for reflecting microwaves reflected by the reflector (RP) as a plane microwave beam. The beam is focused in a concentration point between the reflectors (RP, RE2). #CMT# : #/CMT# An independent claim is also included for a radar echo simulator comprising a microwave emission device. #CMT#USE : #/CMT# Used in a radar echo simulator of a laboratory for emitting microwave (claimed), where the simulator is utilized for generating a complex radio wave in a point of a space, corresponding to phase center of reception antenna of a radar and the wave represents a radar echo and appears coming from a scene or a target e.g. aircraft, or a zone of the space in a predetermined solid angle. #CMT#ADVANTAGE : #/CMT# The device is compact, has less number of the radiation sources, so that the device cost and cost of an electronic microwave signal producing unit are reduced and the encumbrance of the device is reduced. The device is capable of producing the complex radio wave that is equal to sum of plane waves agility in the predetermined solid angle that is practically independent of encumbrance of the radiation sources. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a microwave emission device.
