The receiving voltages after compensation are input to the estimation of signal parameter via rotational invariance technique (ESPRIT) for direction estimation. Different compensation methods in the literatures have been compared to verify the effectiveness of this method, and multiple incident waves of both uncorrelated and coherent characteristics are simulated.Acknowledgment i 摘要ii Abstract iii Table of Contents iv List of Figures vi 1 Introduction 1 2 Signal Model 4 3 Conventional Decoupling Method 6 3.1 MoM-based Method . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 3.2 Calibration Method . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 3.3 Multiple Antenna Induced EMF Method . . . . . . . . . . . . . . . . . . . . 8 4 Decoupling Method with Azimuthal Information 12 5 Covariance Matrix for ESPRIT 14 6 Results and Discussions 17 7 Conclusion 271730066 bytesapplication/pdf論文公開時間:2019/09/03論文使用權限:同意有償授權(權利金給回饋學校)天線陣列互耦補償訊號來向線性偶極天線陣列之互耦補償以改善訊號來向之偵測Coupling Compensation with Azimuthal Information to Improve Direction-of-Arrival Estimation with a Linear Dipole Arraythesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/264304/1/ntu-103-R01942091-1.pdf
