CCD Signal Processor Study.
Abstract
This report presents the results of a study of the application of charge coupled devices (CCD's) to radar signal processing systems. The particular radar problem considered was the detection of satellites at ranges of up to 25,000 NM. A CCD baseline design and tradeoffs are given for this problem. CCD devices were characterized in sufficient detail to construct an accurate computer simulation of their operation. The simulation included all known noise effects in CCD's in addition to the basic functional properties such as charge transfer inefficiency and dark current. Delay line and matched filter configurations were then synthesized from the CCD model and performance of various CCD subsystems ascertained as CCD parameters were varied. Parameter variations included CCD length, clock rate, gate size, tapped weight accuracy, charge transfer inefficiency, and temperature. Results are presented relating study results to achievable performance for various signal processing subsystems. Programmability, bandwidth limitations, sidelobe levels, dynamic range and signal-to-noise considerations are addressed.(Author)
