KOR Electronics introduced the new 1254 12-Bit DRFM system late in 2003. The 1254 has exceptional spurious-free dynamic range, very wide range delay, extremely low noise floor, and extensive integrated digital modulations, including JEM, Doppler and Scintillation. In addition, the versatile Model 1254 DRFM has a large array of programmable ECM techniques.

The Model 1254 DRFM has the growth capability for additional individual DRFM cores, downloadable waveforms for special ECM techniques, higher sample rates as A/D and FPGA technology improves, range extent targets, and clutter simulations. The model 1254 has 16 independent channels, each programmable in range-delay, amplitude and phase/Doppler. Up to 16 fully independent Multiple False Targets (MFT) can be simulated, as well as Extended Target Simulation with up to 16 scatteres in a locked body configuration. Extended Target Simulation is a new application for missile seeker Hardware In the Loop (HWIL) testing facilities.

the Model 1254 DRFM consists of a Memory Card and ADC-DAC Card. The Memory Card contains the Field Programmable Gate Array (FPGA), logic and memory, and stores and manipulates waveforms for a maximum of 16 scatteres /MFT. A two card DRFM card set is required for 16 scatteres/MFT. Since the ADC-DAC Card contains two DACs and one ADC, adding an additional memory card results in two DRFM (3 cards) with the capablilty to simulate 32 scatterers/MFT. Two DRFM occupy 3 slots of a 6U x 160 VME card cage. Four DRFM occupying 6 slots would result in 64 scatterers/MFT. This design is the basis for implementation of the KOR high-fideleity clutter simulation system.

Additional subsystems, including RF up/down converters and Windows based Graphical User Interface can be added to create a high fidelity ECM/Target/Clutter Simulator. Design architecture of the system has been optimized to support customer enhancements.
