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 Array

指導教授 : 江簡富

摘要


本論文以互易定理為基礎,推導出線性偶極天線單元間之耦合效應並補償之,進而將補償後之訊號用於改善訊號來向偵測之準確性。此外也測試偵測多個相干或不相干之入射訊號,並與參考文獻中的其他補償耦合效應之方法比較,進一步驗證本方法之有效性及優越性。

並列摘要


Reciprocity theorem is applied to derive a method to compensate for the coupling effects in a linear dipole array, hence improving the accuracy of estimating the direction-of-arrival of the incident wave. 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.
