Custom large scale integrated circuits for spaceborne SAR processorsThe application of modern LSI technology to the development of a time-domain azimuth correlator for SAR processing is discussed. General design requirements for azimuth correlators for such missions as Seasat-A, Venus Orbital Imaging Radar, and Shuttle Imaging Radar are summarized. Several azimuth correlator architectures suitable for implementation using custom LSI devices are described. Technical factors pertaining to selection of appropriate LSI technologies are discussed, and the maturity of alternative technologies for spacecraft application is examined in the context of the expected launch dates. In particular, it is demonstrated that a custom LSI device is practical for a system as complex as the DMSP.
