AI Technical Summary
In existing low-Earth orbit satellite communications, phase storms caused by high dynamic link distortion result in insufficient robustness of satellite image data transmission, making it impossible to effectively isolate core observation data. Furthermore, conventional methods increase satellite payload weight and energy consumption or lead to bandwidth waste.
By acquiring satellite epoch parameters in real time, the image data is decomposed into basic feature streams and background residual streams. Combined with orbital parameters and channel capacity sequences, multi-level orthogonal amplitude modulation and nonlinear displacement stretching are used to prioritize the transmission of key semantic feature streams, ensuring the stability of decision boundaries in a phase noise environment.
It improves the transmission stability and bandwidth utilization of satellite imagery data in phase noise environments, reduces the demand for onboard transmission power and bandwidth, and ensures the efficient transmission of critical information.
