Abstract :
A novel approach composed of the phase-shift measurement method and the encoding matrix is introduced to solve the problem of the fast measurement and the calibration of phased array antennas. Both phased array antennas and probe are fixed in the whole measurement process. The encoding coefficient matrix is used to control the phase-shift of each phase shifter in phased array antennas. The signal of each phase shifter and the excitation of each channel can be recovered after decoding. In the mean time, the fault of each element can be diagnosed. The simulation of the measurement process of the phased array antenna model shows the correctness and effectiveness of the approach.
