CCD data processor for maximum likelihood feature classification

The paper describes an advanced technology development which utilizes a high speed analog/binary CCD correlator to perform the matrix multiplications necessary to implement onboard feature classification. The matrix manipulation module uses the maximum likelihood classification algorithm assuming a Gaussian probability density function. The module will process 16 element multispectral vectors at rates in excess of 500 thousand multispectral vector elements per second. System design considerations for the optimum use of this module are discussed, test results from initial device fabrication runs are presented, and the performance in typical processing applications is described

Satellite pattern classification using charge transfer devices

The potential uses of Charge Transfer Devices (CTDs) in pattern classification operations are explored. The needs for a hardware-based pattern classifier are established, and a matrix multiplication subsystem based upon a sum-of-products CTD is presented. Applications of the subsystem to the classification of multi-modal Gaussian distributions in general and to LANDSAT data processing in particular are discussed. Finally, the potential impact of this technology on satellite data processing methodologies is discussed.

Satellite onboard feature classification using CCD's

In this paper discrete time analog signal processing applications of CCD's are discussed. The types of computations which can be performed in the CCD technology are discussed and compared with respect to their accuracy and required support hardware. The classification problem encountered in the reduction of multispectral data into features of terrestrial interest are decomposed into a CCD technology based hardware solution. The resulting system is readily implemented with existing and anticipated CCD devices. This system will be projected to spacecraft application.

Charge-coupled device /CCD/ analog signal processing

Analog charge-coupled devices and sampled data filtering have developed into mature disciplines. Each discipline offers the other wide systems advantages where alone it would be impractical. This letter explores these advantages in a number of implementations against the scale of wide low-cost applications.
