| 摘 要： | 在方向依赖的阵元复增益条件下，该文提出一种宽带chirp信号二维角估计新方法。该方法基于信号时变阵列流形结构分析，构造出一种阵列流形时频变换，无需估计和补偿即可消除阵元幅相不一致误差的影响，实现宽带chirp信号二维角闭式解析估计。仿真实验表明了新方法的有效性。

| Abstract: | A novel method is proposed to estimate 2-dimensional (2-D) angles of arrival (AOAs) of wideband chirp signals in direction-dependent sensor complex gain condition. In this method, via the algebraic structure of wideband chirp signal’s time-varying manifold, a manifold time-frequency transform is presented to obtain closed-form 2-D angles estimation and sensor errors elimination. The efficacy of the proposed method is verified by simulation results. |
