摘要
现有研究表明,为保证星载相控阵的工作性能,必须对其进行通道间幅相校准,然而常规方法难以在星载环境中适用。因此国外已开发出REV、CCE与UTE等算法。文章对UTE与CCE算法的性能进行理论分析与仿真,结果表明CCE算法的性能优于UTE。通过对相应算法的分析研究,可为将来的工程应用提供良好借鉴。
To work better, the phase array （PA） in orbit was needed to be calibrated while the normal algorithms didn＇t work well. So a series of algorithms were proposed for that now, for an instance, REV, CCE and UTE and so on. The performance of UTE and CCE were analyzed in the paper. Simulation results showed that UTE was more better than CCE, which was consistent to the theoretical analysis.
