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.
