摘　　要：低零功率对抗技术的发展要求实现电子战系统干扰发射功率控制。提出针对宽带相控阵的单环路数字预失真处理架构。基于多维记忆多项式对单输入多输出的相控阵系统进行数学建模,利用最小二乘法完成数字预失真参数估计,实现对相控阵系统的线性化。在此基础上进行仿真验证,仿真结果表明对0.2~2 GHz宽带干扰发射系统的非线性抑制性能改善约13 dB,为电子战干扰发射系统线性化应用提供参考。With the development requirement of low or zero power countermeasure technology,it is very important to control jamming system transmitting power.A single loop digital predistortion processing architecture for wideband phased array is proposed.Based on multi-dimensional memory polynomial,the mathematical model of single input multiple output phased array system is established.The least square method is used to estimate the digital predistortion parameters and realize the linearization of the phased array system.On this basis,the simulation results show that the nonlinear suppression performance of the 0.2~2 GHz wideband jamming transmitting system is improved by about 13 dB,which provides a reference for the linear application of the electronic warfare jamming transmitting system.
