Broadband DOA Estimation Based on Time Modulated Array

针对传统的无线电测向体制难以适应宽带信号测向问题,提出了基于时间调制阵列的宽带信号测向方法,分析了利用二单元时间调制阵列进行宽带信号测向的基本原理和流程。该方法具有硬件和算法复杂度低,精度高、信号适应性强等优点。仿真结果以及典型的无人机信号测向实验证明了该方法的有效性。

Conventional DOA estimation method encounters a barrier when exploited in the direction finding for broadband sig. nals. This manuscript has proposed a novel direction finding method for broadband signals based on the time modulated array. The fundamental principles and procedures of the proposed method have been analyzed in detail,which has advantages in the hardware and algorithm complexity. Simulation results and experiment for UAV signals are provided to verify its effectiveness.
