PARABOLIC ANTENNA is most regularly used to install the type of radar antenna project. Parabolic antenna consists of a parabolic reflector and a circular reflector located in the point of interest of the light source. Parabolic reflector is made of metal, on a regular basis a metal frame covered with wire mesh on the inside. The metal mesh width of the slot will have to be less than λ / 10. The metal coating is formed to act as a mirror reflector of radar energy.
THE OPTICAL ANALYTIC GEOMETRY and for the entire reflected light of the reflector of this type will be parallel to a parabolic law which gives us a single ideal no reflected light is parallel to the main axis of the side lobes axis. The field leaving the feed horn spherical wave front. As each part of the wavefront reaches the reflecting surface, it is shifted by 180 degrees, the phase angle and in all sections of the field in the parallel paths of trip will be sent out.
This is an IDEALIZED RADAR ANTENNA and produces a pencil beam. If the reflector has an elliptical shape, then it is going to produce a fan beam. Surveillance radar used within the horizontal and vertical planes of the two different curvatures, in order to achieve the required pencil beam in azimuth and elevation in the classical cosecant squared fan beam
