Methods: the mathematic method is used to find a uniform expression for frequencyaliasing matrix of different resolution images.
方法：用数学方法求解对应于低分辨率遥感图像的统一频谱混叠。

The frequencyaliasing due to sub-Nyquist sampling can be resolved by the proposed frequencyaliasing resolving algorithm and information from the time-delay channel.
文中，欠采样所引入的频率模糊由增加的延迟通道提供的信息加以消除，并提出了相应的频率解模糊算法。

The experimental results show that the method can overcome the limitations of the critical angle between the object and reference beams, and omit the frequencyaliasing.
