分析了合成孔径雷达干涉相位图中噪声的产生原因,讨论了相位噪声不仅与相干性有关,还与干涉图视数有关,成功地模拟了不同视数下的加噪相位图。
The reason of the noise in the interferogram of synthetic aperture radar is analyzed. The phase noise is discussed not only related to the coherence but also related to the number of the interferogram, and the noise phase diagram under different apparent numbers is successfully simulated.
