Abstract
The deliverable sets some constrants on the requirements for a X-band SAR mission: Considering the orb ital constraint necessary to cover latitude characteristics of the Italian and European territory and the analysis carried out in Section 8 a requirement on orbital inclinations lower than 55' has been set. Similarly, assuming an azimuth resolution of 3m, to limit the Doppler centro id decorrelation to the 35%, the maximum angular variation of the aspect angle, or equivalently of the orbit crossing, is 0.1°, for a velocity of 7 The level of Noise Equivalent SigmaZero (NESZ), as well as the azimuth ambiguity level have been set on the basis of the CSK values and by considering the constraints associated with the compact technology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
