频率分集阵列稳态波束形成方法
Static beamforming method of f requency diverse array
摘要
Abstract
Focused on the time‐varying property of the transmit beampattern of the frequency diverse array , a static transmit beamforming method is proposed to control the beampattern of the pulsed frequency diverse array , and the characteristics of its radiating pattern are studied . With a tiny progressive incremental frequency shift applied between the adjacent antenna elements , a range‐angle dependent radiating pattern is achieved . Compared with the conventional phased array , the frequency diverse array is low in price and small in complexity without the use of phase shifters , which enables it to be suitable for the miniaturization design of an array antenna . Moreover , its range‐angle dependent characteristic significantly enhances the flexibility of antenna beam scanning . Simulation experiments demonstrate the effectiveness of the proposed method .关键词
