Abstract

Minimum Variance Distortionless Response(MVDR) algorithm for wideband coherent signals based on data reconstruction is proposed.Based on the sampling theorem, the output of different array elements at the same time is taken as the sampling of the continuous line array, and the data of the time domain is re-sampled. The method is used to estimate the azimuth of the broadband coherent source and a method of obtaining the focus error is proposed to analyze the performance of the MVDR algorithm of the wideband coherent source. Computer simulation of the FFT interpolation method and data reconstruction method of the azimuth estimation results show that for the broadband MVDR algorithm, data reconstruction method than the FFT interpolation method has better resolution probability and lower RMS error.
