Abstract

Adaptive beamforming is a technique to suppress the interference coupled to the antenna through the antenna sidelobes and minimize the corruption ofthe signal of interest by means of adaptively tracking the source of interference with the nulls of radiation pattern [1-2]. Adaptivity is vital to a host of mission-critical applications, for which jamming suppression in a radar has been studied extensively [3]. As the time-bandwidth product (TBWP) of the adaptive processor increases, the computational burden rapidly exceeds the capabilities of the state-of-the art integrated microelectronics technology. A computation power of 1013 bps may be required. Insufficient parallelism has limited performance of electronic radar processors to approximately 50 dB jam suppression over the bandwidth of 1 MHz.
