Abstract: System and method for array antenna failure detection and antenna self-correction are introduced. In the array antenna failure detection and antenna self-correction system, a signal analyzer is employed to perform gain analysis so as to perform gain attenuation/compensation, and a DC offset generator is employed to generate a set of known offset amounts which are added to signals, so that, at the receiving end, a phase offset amount can be derived based on comparisons with the original signal, and antenna correction can then be performed accordingly. In this way, computational complexity of the system can be reduced, and the speed of antenna correction can be increased.
