Abstract:

This final technical report describes an experimental R and D program to apply charge transfer device CTD technology to the design and fabrication of a three-pulse MTI, and demonstrate its capabilities in an actual radar system. The specified 50 dB cancellation ratio was achieved. The CTD is a sampled data integrated circuit in which samples are stored and processed as discrete packets of charge. Utilizing a continuous range of amplitude, CTDs eliminate the cost, volume, and power penalties inherent in the AD and DA conversion used in digital systems, while retaining the advantages of stability and small size. The design trade-offs necessitated by using devices available at the beginning of the contract, and subsequent limitations are discussed. The present state-of-the-art CTDs would eliminate the need for the multiplexing used for this contract and reduce the hardware by a factor of four. CTD technology offers stable, low cost alternative to MTI design. In addition, signal processing methods such as pulse compression, correlation, chirp z transforms and allied techniques are under investigation and should be considered by the system designer.
