The Measurement Method of Echo Highlights in Low Frequency

Article Preview

Abstract:

Methods which are MVDR beam-forming, STMV beamforming and a method using MVDR beamforming with copy correlation are using to measure highlight of targets echoes at low frequency. Compared with conventional beam-forming, the three methods restrain noise and resist reverberation better. To reduce calculation, firstly, as the azimuth measured by using Split array cross-correlation beamforming the center, and then the neighboring area scanned using MVDR focused beamforming. Therefore, this highlight of echoes research measures have high precision and practical.
