An Algorithm of Weak Signal´s Detection on the Condition of Strong Interfernce

An algorithm which can detect weak signals on the condition of strong correlated interference is designed in the paper. The algorithm based on conventional beam forming (CBF) can put nulls on given directions. And the weights only relating to interference´s direction is given in the paper. Comparing to adaptive methods, the algorithm is robust and the calculation account is smaller. Simulation results show the algorithm can put null on the strong interference´s direction, getting a clear bearing track recorder while the CBF even can´t get the target´s track.
