Performance analysis and advancement of self-steering arrays for nonsinusoidal waves. II

For pt.I see ibid., vol.30, no.2, p.161-7 (1988). A self-steering array system for beam forming with nonsinusoidal waves was analyzed and computer-simulated. An alternative beam-steering mechanism is described and computer-simulated for performance evaluation. It uses a linear-regression processor (LRP) that is less sensitive to thermal noise than the threshold-detection scheme. In the presence of thermal noise, the LRP yields a negligible error in pointing a main beam toward a desired look direction. A design of a variable-delay circuit is presented for the advancement of the delay-time-adjustment mechanism of a self-steering array system that has been developed in theory
