Abstract EN
The paper presents a new method to estimate the two-dimensional (2D) direction of arrival (DOA) (the azimuth angle and the elevation angle) of electromagnetic signal emitted from a single communication station.
This method is passive and accurate in the case of low signal-noise ratio (SNR) based on the virtual time reversal (VTR) theory.
In order to illustrate its principle, the theoretical formulas of VTR direction finding with uniform circular array (UCA) are derived firstly.
Based on these formulas, the implementation scheme for estimating azimuth angle and elevation angle passively is then provided.
In the derivation, the strict mathematical proof for compressing planar search area to a curve line is proposed, reducing the complexity of VTR algorithm greatly.
Finally, the simulation experiments are performed to validate the performance of VTR algorithm.
The results show that the VTR method is effective and it delivers accurate DOA estimation in the case of low SNR.
