Abstract |
AB |
[EN] A reflector antenna for synthetic aperture radar, having a reflector including a reflector surface, a vertex, and an optical axis. The reflector antenna also as a plurality of antenna elements arranged side by side and in a row, for transmitting radar transmission signals and receiving radar reception signals produced from a reflection on a surface. The reflector is designed as a one-dimensional defocused reflector having two focal planes. The optical axis coincides with the line of inter-section of two imaginary planes extending at right angles to one another. The reflector has, in a first (X-) plane, a first (X-) focal plane that extends at right angles thereto and to the optical axis, and, in a second (Y-) plane, a second (Y-) focal plane which extends at right angles thereto and to the optical axis. The second (Y-) focal plane is at a greater distance from the vertex than the first (X-) focal plane. |
