Self-cross Phase Calibration Method of Oversized Front Distributed Phased Array Radar

Abstract

For oversized front distributed phased array radar, the conventional phased array radar calibration algorithm can not work. This paper presents the combination of self-calibration and cross-calibration algorithm. Analyzed the error sources of the oversized front distributed phased array radar. Established the error model of the oversized front distributed phased array radar. Elaborated the self-calibration and cross-calibration principles and methods. This method is extended to the phase array radar from units. Finally, we carry out the self-intersecting phase calibration simulation experiments. The simulation results show that the algorithm can significantly improve the oversized front distributed phased array radar sidelobe level.
