A High Dynamic Range Receiver for the Radar Open System Architecture

VME-based systems have been used for over 28 years as an open system architecture for processor and IO devices. Similar to the ubiquitous PC, The VERSAmodule Eurocard bus (VMEbus) computer architecture was developed in 1980 to provide an open platform for any manufacturer to provide hardware that would conform to both the electrical specifications and mechanical form factor. The most recent version of the VME standard is VME64, offering improvements in bandwidth among other things. While the availability of processor and I/O modules for VME have steadily increased over the years, high performance, digitally-controlled, microwave receivers remain highly customized for the specific application. For radar applications, high spurious-free dynamic range and pulse processing capabilities are important features of a microwave receiver.
