Abstract :
An approach to systolic adaptive array with sidelobe control is proposed in this paper. According to the structure of the QRDSMI (QR decomposition-sample matrix inverse), the QRDSMI algorithm is converted into systolic parallel pipeline structure to improve its real-time processing capability. Low sidelobe of the beam is obtained by constraining the static steering vector with Tschebyscheff coefficients. Simulation results verify the validity of the algorithm.
