Vertical array signal recovery method based on normalized virtual time reversal mirror

Abstract Focusing on the vertical array source signal recovery method, aiming at estimation deviation caused by environment mismatch in engineering application of virtual time reversal mirror technology, this paper proposes normalized technology through theoretical derivation and analyzes performance under change signal-to-noise ratio simulation. Finally, practicability method effectiveness model correction are verified experimental data. The data processing results show that level error based algorithm is less than 5.2dB. In paper, correlation spectral structure recovered about 5% higher traditional method.
