Abstract
A charge injection device (CID) solid-state video sensor/focal plane processor is described which can be used to implement Hadamard transform techniques to reduce video band-width. This device can be operated in two modes. In one mode, the output is a normal video signal. In the second mode, the output is the Hadamard transform of the image. This approach offers an opportunity to relieve the small size and low power requirements imposed by mini-RPV and guided weapon antijam video data link applications by performing the transform processing function of the airborne encoder directly on the image plane. A description of the CID imager, the one- and two-dimensional Hadamard transform implementation of the focal plane processing chip, and preliminary test results are included.
