Abstract :
The demand of detecting treat signals between 18 and 110 GHz has created interest in the development of broadband direction-finding system at the millimeter-wave frequency range. A novel design for a direction-finding system is presented, covering frequency bands from 18 to 110 GHz. The use of a flat splash reflector makes it possible to build the system without a rotary joint. Dual polarization detection is realized based on the design of symmetrical orthogonal-mode transducer
