【 摘 要 】

Based on model features of the vector sensor array signals, the paper transforms the time delay of broadband signals in time domain into the phase shift of different sub-bands in frequency domain to realize accurate time delay, and uses Hilbert Transform to construct analytic signals to form a fast vector array adaptive beam forming algorithm flow. The verification result with experimental data shows that this algorithm has much better target resolution capability than conventional beam forming algorithm. With the increase of 4-6dB in target detection capability, it has bright application prospect.
