本文基于波束指向精度是相控阵天线重要的性能指标,频率色散误差是一种主要的天线指向误差,提出了一种非延时的色散误差补偿方法,给出了非均匀平面阵的色散误差机理和全空域的色散误差仿真结果.同时,通过将其对应的最大瞬时带宽进行理论推导,给出了基于指挥控制系统的补偿办法.结果表明:理论计算结果和仿真结果一致.
Non-delay Correction for Planar Phased Array Dispersion Error
Based on the fact that beam pointing accuracy is an important performance index of phased array anten-na,and frequency dispersion error is a major antenna pointing error,a non-delayed dispersion error compensation method is proposed in this paper.The dispersion error mechanism of non-uniform planar array and the dispersion error simulation results of the whole space are given.At the same time,the compensation method based on command and control system is given by theoretical derivation of the corresponding maximum instantaneous bandwidth.The re-sults show that the theoretical calculation results are consistent with the simulation results.
