摘要：
Narrow band interference (NBI) is one of the main radio frequency interferences. The presence of NBI has serious influence on interferometric phase. And it can lead to digital elevation model (DEM) reconstruction error. The interferometric phase interfered by NBI is deduced, and the sensitivity of interferometric phase to the parameters of NBI is also given in this paper. By simulation, effects of NBI on P band InSAR interferometric phase and DEM reconstruction are analyzed. The conclusions are that the amplitude of NBI after imaged is approximately sinc function of azimuth time, and NBI brings bright strap in the range direction in SAR image. In addition, interferometric phase is not sensitive to the frequency of NBI but sensitive to the power of NBI. And with the increase of the interference to signal ratio (ISR), both interferometric phase error and DEM error increase.
