英文摘要:
      Eigendecomposition algorithms for high resolution direction of arrival (DOA)estimation have good performance. Based on the practical application of underwater array signal processing, eigendecomposition algorithms for DOA estimation are studiedusing a C30-chip hardware. The result provides an important base for practical application of high resolution teqnique and design of real-time signal processing system. A highresolution C30-chip hardware experimental system is constructed. Pisarenko, MUSIC,Johnson and Mininorm methods for estimating DOAs are implemented in the systemA great number of computer simulation and the experiment in a big anechoic watertank show that the high resolution C3O-chip hardware experimental system has advancedstatistical properties and real-time properties in DOA estimation of underwater targets.
