“…The MTF is of fundamental importance for sensor specification and design, as it specifies the spatial response of imaging systems [2,10]. The MTF represents the contrast ratio of the output to the input image as a function of frequency.…”

The simulation of remote sensing images is a valuable tool for defining future Earth Observation systems, optimizing instrument parameters, and developing and validating data processing algorithms. A scene simulator for optical Earth Observation data has been developed within the Environmental Mapping and Analysis Program (EnMAP) hyperspectral mission. It produces EnMAP-like data following a sequential processing approach consisting of five independent modules referred to as reflectance, atmospheric, spatial, spectral and radiometric. From a modeling viewpoint, the spatial module is the most complex. The spatial simulation process considers the satellite-target geometry, which is adapted to the EnMAP orbit and operating characteristics, the instrument spatial response, and sources of spatial non-uniformity (keystone, telescope distortion and smile and detector co-registration). The spatial module of the EnMAP scene simulator is presented in this paper. The EnMAP spatial and geometric characteristics will be described, the simulation methodology will be presented in detail, and the capability of the EnMAP simulator will be shown by illustrative examples.

“…Classically, images of sinusoidal gratings have been used for OTF lens measurements. When a focal plane array (FPA) images the grating the discretization means that the FPA must be moved relative to the image to give minimum and maximum MTF curves [17]. Sinusoidal laser interference patterns have been used by Marchywka and Socker [18], and laser speckle techniques can also be employed [19].…”

“…S. K. Park proposed to use average MTF to evaluate the imaging quality of discrete imaging systems based on point spread function Fourier transform [7]. J.Feltz used a line-array CCD signal in the sinusoidal input signal period to output the maximum value and the minimum value according to the contrast definition of MTF so as to offer the line-array CCD and expression of phaserelated MTF [8]. Song min experiments verified that the experiment results agree with Feltz's theoretical calculation [9].…”

Abstract.As an image-spectrum merging technology, hyperspectral imaging has been used in battlefield reconnaissance rapidly．Based on response of CCD to the sine input signal, the period and extremal positions of output signal were analyzed and simulated. According to the definition of MTF based on contrast, three expressions of the average MTF of line-array CCD were presented and compared with those based on Fourier transform method. Finally, the average MTF of line-array CCD is confirmed. Accordingly, the characteristics of modulation transfer function of line-array CCD are studied. The simulation results indicate that the frequency increase, while at Nuquist frequency, the effect of the initial position, which becomes much stronger with frequency increase, while at other frequency, the effet of the initial position is weak. In the frequency range of |ζ |>0.1%,the effect of the initial position on MTF can be ignored.
