A self-steering array for nonsinusoidal waves

A self-steering array system is described for beam forming with nonsinusoidal waves. The array system electronically steers a main beam in the direction of the source from which the wavefront is arriving without prior knowledge of the source location. The principle of monopulse tracking radar is applied to the array system so that the angular coordinate of the source can be determined with respect to the array axis. If the source is in motion, it can be tracked on pulse-to-pulse bases. Finally, the self-steering array system is advanced further to suppress the additive thermal noise present with the incoming signals, and to achieve good angular resolution and accuracy.
