Theoretical analysis of the super agile high resolution remote sensing satellite for maneuvering imaging
In view of the new features of super agile remote sensing satellites, including large angular velocity of 6(°)/s, large angular acceleration of 1.5(°)/s2, and the imaging parameters tending to change in different time and space, super agile maneuvering imaging characteristics were analyzed and imaging parameters were simulated. The variation of resultant velocity was precisely calculated based on the complicated model of maneuvering imaging. On this basis, together with the computational formula of SNR and MTF, the change of line rate, TDI stages, MTF of attitude stability, MTF of synchronization error, and MTF of drift error with the variation of the maneuvering angular velocity in different imaging conditions were comprehensively analyzed, which provides an important foundation for the design of super agile maneuvering imaging satellites, particularly for the imaging electronics of the satellites.
