Abstract
The multiple beam radar system uses multiple simultaneously transmitted beams of high frequency energy to identify scatterers that are located in a predetermined volume of space. This multiple beam radar system simultaneously transmits several beams of high frequency energy, produced by an antenna which operates in a mechanically scanning mode, and simultaneously receives the returned radiation, which constitutes components of this narrow beam that have been reflected off scatterers located in the path of the beam. The transmitted (and thus received) frequency of each beam is different, providing information relating to the presence, locus and characteristics of the scatterers by analyzing the plurality of received beams. Each of the simultaneously transmitted beams are focused in a different direction by virtue of the fact that the antenna transmits beams of different frequencies in different directions, with the direction of each beam and the separation between beams being a function of the transmitted frequencies and the characteristics of the antenna.
