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 a variable ratio power network (amplitude balance control) for adjusting the relative phase and amplitude in two or more antenna branches to steer a null on an interference source. A digital controller compares a signal which includes a representation of the interference level to a previously sampled value to note improvement or not and adjusts the delay lines and amplitude balance accordingly.
