The thesis reports on an investigation of a practical solution to the problem of providing covert, secure protection to the video channel of a remotely piloted vehicle (RPV) down-link. Spread spectrum technology employing acoustic surface wave devices and Golay complementary code sequences are used. Bandwidth reduction of the video data to a data rate of 200 kilobits per second is assumed. The thesis effort results in a transmitter/receiver combination with many of the desirable qualities of a video link for military RPV employment in a hostile environment. The hardware contains modifications that were made to facilitate system testing. Tests results are reported.
