DBF Algorithm of Weak Signal Extraction From the Background of Strong Signals
Gao Yong · Systems engineering and electronics · 2001
A blind DBF algorithm of weak signal from the background of strong signals is proposed. If the space separation between strong signal and weak signal more than one beam width, the algorithm proposed can effectively extract weak signal without knowing weak signal's direction of arrival. It has small computation load and some robustness with system errors. The direction information of the strongest signals can be gained system errors. The simulation results verify the algorithm.\;
