RAnge Delay Emulator (RADE)

There is a need to more accurately test Digital RF Memory (DRFM) devices in an Installed System Test Facility (ISTF) in order to reduce cost and time required in comparison with flight testing. The Joint Integrated Mission Model (JIMM) is a mission-level, discrete-event, general-purpose simulator that is capable of integrated operation with real hardware components. As such it is ideally suited to act as an ISTF for DRFM testing, but to do so must have a means of providing coaxially-injected RF signals with real time emulation of range delay to distances of 27,000 nautical miles (Nmi) without degradation of the signals. In order to satisfy this objective, in Phase I of this contract Systems & Processes Engineering Corporation (SPEC) plans to leverage our experience with the development of the Agile Digital Effects Processor (ADEP™) technology, to create the Range Delay Emulator (RADE). SPEC''s ADEP™ combines RF signal characterization, DRFM and arbitrary waveform generation capabilities. Current ADEP™ systems include similar capabilities, and these will be extended to meet RADE requirements.
