The sensor MTF is not only an important descriptor of image quality, but also determines the potential for spatial mixing of spectral signatures in hyperspectral systems. The HYDICE total system MTF has been measured from flight imagery of targets of opportunity, including the Mackinaw Straits Bridge in Michigan and the Chesapeake Bay Bridge at Annapolis, Maryland. The procedures used to derive the MTF are described, and the results are compared to pre-flight laboratory measurements made at Hughes-Danbury Optical Systems. The inflight MTF measurements at 0.5 cycles/pixel are in the range 0.5 to 0.65 in-track, and 0.4 cross-track, which are consistent with the pre-flight measurements. |
