Multi-target pair-matching method based on angle information in transmit/receive-receive synergetic High Frequency Surface Wave Radar

In the past few decades, the target location methods in transmit/receive-receive (T/R-R) synergetic High Frequency Surface Wave Radar (HFSWR) have received extensive attention from the signal processing community. However, there are few studies on the method of parameter pair-matching for multi-target scene. In this paper, a computationally efficient multi-target pair-matching method based on angle information only in T/R-R synergetic HFSWR is developed. The proposed method is realised by dealing with three vectors composed of the first column, the first row and diagonal entries of the correlation matrix, instead of performing the singular value decomposition (SVD) of the correlation matrix. Simultaneously, the proposed method is a computationally efficient subspace algorithm, which only uses the angle information to complete the purpose of multi-target pair-matching. The simulation results are presented to demonstrate the effectiveness of the proposed method.
