Multi-Step Amplitude Quantization for Ultralow Sidelobe Phased Arrays by Direct Optimization Synthesis

摘要

In this paper, a new amplitude quautization synthesis method for ultraiow sidelobe phased arrays is proposed,which is based on the constrained nonlinear optimization algorithm. By introducing a set of critical constraint conditionsinto the optimization model, we can directly quantize the amplitude distribution instead of replacing it with a continuousequivalent aperture antenne The mutual coupling and the element patterns are also considered in the quantizationsynthesis. Finally, some array simulation results are given to show the effectiveness of the method.
