Abstract
Many of the advanced sensor concepts, which are either recently developed or are under development, utilize one or more large mosaic arrays of detectors. It has been shown through various studies that the only practical way to handle the very high rates of data produced by these large mosaic arrays is to perform a variety of signal processing and 1 data compression functions on the focal plane by using some form of focal plane processing. Tn this paper, we have postulated a focal plane layout and a scheme to carry out various processing functions on the focal plane using Charge Coupled Devices (CCD's). The performance of this proposed focal plane processing scheme under a host of error sources has been evaluated through simulation and emulation. The parametric performance results are presented in this paper.* The simulation was carried out using a representative Monte Carlo statistical method and six error sources were used to evaluate the performance of focal plane processing schemes under various input signal to noise ratios. A simulation of the performance was carried out under the presence of all of the error sources and results such as the relationship between output signal to noise ratio vs the number of TDI stages were obtained.
