The detection and cataloging of near-Earth asteroids and comets is of considerable current interest in the international scientific and policy making communities. Electro-optical technology developed by MIT Lincoln Laboratory for satellite tracking applications is well suited to the detection and tracking of faint near-Earth objects. This technology includes state-of-the-art, large-format CCD's with noise and readout performances which considerably exceed those of CCD's employed in current NEO search systems. The performance of the Lincoln Laboratory CCD's and surveillance techniques enables the construction of a NEO search system using 1-meter class telescopes while retaining the performance of the Spaceguard system which proposes 2.5-meter class telescopes. Use of smaller telescopes results in considerable system construction cost savings. The performance of the new CCD's and the associated support system has been demonstrated as part of ongoing, routine device testing and field operations. In 1993, field measurements demonstrated the performance of the CCD technology by using a 1024 by 1024 pixel format CCD mounted on a 31-inch telescope to conduct a limited search for asteroids. Field test efforts in 1995 will employ the next generation CCD, with a 2560 by 1960 pixel format, to validate the technology for use in an NEO search.
