The phase retrieval problem from single intensity measurement was also discussed in terms of the properties of analytical function or under consideration of sampling theorem.

由单强度测量来恢复相位问题，也有过讨论，可以利用解析函数特有性质或应用取样定理来实现相位恢复。

Furthermore, taking phase error of RF front-end, sampling error of high-speed ADC and the size of array into consideration, the image quality of synthetic aperture DSMR is still poor.

受射频前端相位误差、ADC采样误差及阵元个数有限的影响，综合孔径直接采样微波辐射计成像质量仍然较低。
