Synopsis  : 

An eigendecomposition technique (Pisarenko technique) is used as a high resolution technique to model the holographic imaging (detecting) problem. Ultrasonic waves are used for imaging a buried object. The in-line holography is employed. The performance has been investigated for different values of signal to noise ratio(SNR). The results demonstrate the enhanced performance capability of the combination of Pisarenko and holographic methods. Also the method showed much better performance compared with Fourier transform.
