| Abstract: | Data characteristics and compression methods of hyper-spectral interferograms are firstly investigated in this paper.Motivated by the needs of HJ-1A satellite,a preferable compression method suitable for satellite application is then developed.The compression algorithm is implemented on hardware language and hardware circuit.The designed compression encoder is evaluated to be simple,reliable and real-time.Now the encoder is working stably on orbit and the image quality is highly thought of by the user. |
