摘要

为了同时获得稀疏和恒定模数激励，以降低阵列的复杂性和相邻元素的相互影响，我们开发了一种通过交替优化-交替乘法器方向法的新型算法。该方法以总发射功率为目标函数，同时优化激励的稀疏性和振幅。数值结果验证了该方法的有效性。

Phase-only transmit beampattern synthesis with sparse arrays via alternating optimisation-alternating direction of the multipliers method

To get simultaneously sparse and constant modulus excitation to reduce the complexity of the array and the mutual effect of neighbouring elements, a novel algorithm via alternating optimisation-alternating direction of the multipliers method is developed. This method uses the total transmitting power as the objective function to optimise the sparsity and the amplitude of excitation simultaneously. Numerical results are provided to verify its effectiveness.
