摘　　要：脉冲调制中波发射射频采用标准强度增益分析实施补偿,忽略了相对公共相位误差的影响,导致增益补偿结果存在失真情况。因此,提出脉冲调制中波发射射频强度增益补偿方法。估计脉冲调制中波的峰值脉冲能量,并结合脉冲能量块相对公共相位误差解析其相噪,通过划分场区分析射频强度的辐射场串扰值,构建记忆多项式增益补偿该串扰值。实验结果表明:依据所提方法应用后得出的增益补偿结果,未出现失真情况,补偿效果较好。The RF transmission in pulse modulation adopts standard intensity gain analysis for compensation,ignoring the influence of relative common phase error,resulting in distorted gain compensation results.Therefore,a method for compensating the RF intensity gain of wave transmission in pulse modulation is proposed.This article estimates the peak pulse energy of the pulse-modulated medium wave and analyzes its phase noise by combining the relative common phase error of the pulse energy block.It analyzes the radiation field crosstalk value of RF intensity by dividing the field area and constructs a memory polynomial gain to compensate for this crosstalk value.The experimental results show that the gain compensation results obtained after the application of the proposed method show no distortion and a good compensation effect.
