摘要:
针对频率分集阵列（Frequency Diverse Array, FDA）发射波束的距离和角度耦合问题，提出一种基于均匀圆形频率分集阵列的非线性增长频偏方法。首先分析UCFDA的阵列结构，并推导基于线性频偏的发射信号处理模型；接着引入四种非线性频偏，研究基于非线性频偏的发射信号处理模型。 数值仿真表明，与线性频偏相比，提出的四种非线性频偏能解决距离和角度的耦合问题，且具有较高的主瓣分辨率。
Abstract:
Aiming at the problem of range and angle coupling in frequency diverse array (FDA) transmitting beam, a non-linear increasing frequency offset method based on uniform circular array frequency diverse array (UCFDA) was proposed. Firstly, the array structure of UCFDA was analyzed, and the transmitting signal processing model based on linear frequency offset was deduced; then, four kinds of non-linear frequency offset were introduced to study the transmitting signal processing model based on non-linear frequency offset. Numerical simulation results show that, compared with linear frequency offset, the proposed four nonlinear frequency offsets can solve the coupling problem of range and angle, and have higher main lobe resolution.
