摘要
该文针对宽带步进频率收发信号,根据高分辨率一维距离像的多散射中心数学模型,分析了当目标运动时的距离相位关系,并推导了目标一维距离像的偏移因子和发散因子公式,对多普勒效应的影响进行了深入的研究。通过对高分辨率步进频率毫米波目标模型的计算机系统仿真,算法和分析得到了验证,并得到了运动目标速度补偿条件。
The distance-phase variation of one-dimensional range profile for moving target is analyzed,base on the mathematical model of high-resolution multi-scattering centers one-dimension range profile,for the broadband stepped frequency transceiving signal.The shift factor and divergence factor of one-dimension range profile are derived,the influence by the Doppler effect on one dimensional range of the target is analyzed deeply.The simulation results,with high-resolution model of millimeter wave of stepped frequ...
