CCD spectrum analysers

Several types of real-time CCD spectrum analyzers are discussed with reference to their characteristics and applications. These include spectrum analyzers based on the chirp-Z transform, the sliding chirp-Z transform, the prime number transform, and swept split electrode filters. The CCD analyzers are shown to have a low power consumption, compactness, light weight, and low cost in volume protection. Their applications range from medical ultrasonics to intercept receivers and synthetic aperture radar.
