Abstract
In coherent pulse-Doppler radars, the signal processing is frequently performed by a digital processor, or by the combination of an analog pulse compressor followed by a digital processor. Traditionally, digital processing is attractive for one or both of the following reasons: complicated signal processing algorithms can be implemented using commercially available building blocks (i.e., digital ICs) and signals with a large dynamic range can be accommodated. However, in applications involving modest dynamic ranges (≈8 bits), analog signal processing offers the potential for higher throughput rates in a smaller, lower power processor than would be possible with a digital implementation. Except in the area of pulse compression, almost all past attempts to realize the potential advantage of analog signal processing have met with only limited success. In particular, conventional charge-coupled devices (CCDs) have not gained wide spread acceptance in commercial or military systems because they have not provided sufficient cost, power and throughput advantages over digital technology.© (1987) COPYRIGHT SPIE--The International Society for Optical Engineering.
