研究了频率步进高分辨率毫米波这一维距离像的成像方法，讨论了由于Ｉ／Ｑ正交相干解调通道不平衡对一维距离像成像的影响，提出了基于矩阵奇异值分解（ＳＶＤ）法分解出有用信号子空间，由此求取线性变换，对正交相干通道不平衡进行校正处理的方法，并利用目标散射点的回波模型进行了计算机仿真，其结果表明，该方法是有效的。
The method of 1 D imaging for frequency steppping high range resolution MMW rader was studied. The error of a quadrature coherent I/Q channels was discussed. The error correcting method with SVD of matrix was presented. By use of the echo model, the computer simulation was carried out. The simulation results show that the method is effective.
