<P>PROBLEM TO BE SOLVED: To provide a phased array-antenna inspection system, phased-array antenna inspection apparatus and phased-array antenna inspection method for accurately inspecting and correcting the functions of a phased-array antenna, and to provide a phased-array antenna which is accurately function-corrected from inspection results obtained therefrom. Ž<P>SOLUTION: A transmitting-side antenna element 20a and a receiving-side antenna element 30a, and a transmitting-side antenna element 20b and a receiving-side antenna element 30b are proximately disposed face to face. In a state with the phase of the transmitting-side antenna element 20b fixed, the phase of the transmitting-side antenna element 20a is changed; and reception power is measured and a minimal value is calculated from a result of the measurement, thereby performing function inspection on the phased-array antenna 2. If there is a phase shift, the phase shift is corrected. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
