Abstract
The object of this invention is to reduce the adverse system performance effects resulting from antenna pattern sidelobes. It has particular application to the time reference scanning beam of the international microwave landing system (MLS) where sidelobe energy reflecting into the mainbeam at the receiver antenna introduces a timing measurement error. It also has application to systems such as height finding radar where signals entering through antenna pattern sidelobes degrade system performance. This invention describes methods and apparatus for system performance enhancement through the application of sidelobe amplitude and phase control.
