摘要:
针对多载波调相雷达信号因具有较高的包络峰均比而易受功率放大器非线性影响的问题,该文利用Saleh非线性模型分析了功率放大器非线性效应对多载波余码相位调制(MCPC)雷达信号的一维距离像的影响,采用单个MCPC脉冲连续两次发射的信号结构和回波信号自相关的方法提取非线性参数,对MCPC雷达信号的非线性效应进行补偿。理论分析和仿真结果表明该方法可以分离非线性与多普勒效应,不仅使非线性补偿过程免受多普勒和噪声影响,且能保留多普勒信息。
Abstract:
In view of the problem that the high peak-to-mean envelope power ratio(PMEPR) of multicarrier complementary phase-coded(MCPC) radar signal is easily influenced by the power amplifier nonlinear effects,the influences of power amplifier nonlinear effects on MCPC radar signal range imaging are analyzed by citing Saleh power amplifier nonlinear model.A new MCPC radar signal structure of transmitting single pulse twice and nonlinear parameters extraction approach of echoes self-correlation are proposed for power amplifier nonlinear effect compensation.Theoretical analysis and simulation results show that: the proposed approach can separate nonlinear effects and Doppler influences;the compensation procedures are immune to Doppler and noise;Doppler information in echoes can be reserved during compensation.
