Adaptive Steerable Null Antenna Processor.
Abstract
An object of the invention is to provide a steerable null antenna processor, in which the null developed during reception is also maintained during transmission. According to the invention, a receive-transmit steerable null antenna processor includes incrementally adjustable delay lines and an amplitude balance control network (variable ratio power) for adjusting the relative phase and amplitude of two or more antenna branches to steer a null on an interference source. Least-mean-squares loop control including In phase-Quadrature correlation provides feedback control signals which are converted to digital form to adjust the delay lines for phase and amplitude balance.
