sidelobersniveau
Sidelobersniveau is a term used in signal processing and antenna theory. It refers to the ratio of the power received in the main lobe of an antenna's radiation pattern to the power received in its sidelobes. The main lobe is the direction of maximum sensitivity and radiation for an antenna, while sidelobes are smaller lobes that radiate in other directions. A high sidelobersniveau indicates that a significant portion of the antenna's power is being transmitted or received in unwanted directions, which can lead to interference and reduced signal quality. Conversely, a low sidelobersniveau means the antenna is more directive, focusing its energy primarily in the desired direction.
Antenna designers strive to minimize sidelobes for various applications. In radar systems, high sidelobes can cause
