摘要：

The electronically steerable parasitic array radiator (ESPAR) is a smart antenna based on the adjustment of reactances at parasitic elements. A new blind beamformer is presented, for use with reactance domain arrays, such as the ESPAR. Two stochastic gradient algorithms work concurrently so that two distinct cost functions are simultaneously minimised. Results show that the new blind beamformer presents a faster convergence and a lower steady-state mean squared error.
