Research Institution
SA Photonics’ Jammer Emulator (JEM) is a flexible and programmable wideband DRFM Jammer Emulator intended to be able to rapidly evaluate the impact of new threat waveforms. JEM is a high resolution, dual channel jammer simulator that supports large varieties of DRFM and ECM emulation capabilities. A software defined digital signal processing implementation ensures precise and consistent jammer simulation. JEM operates over frequencies from 100MHz to 18GHz with over 100dB signal dynamic range (>70dB instantaneous dynamic range). The base configuration provides two channels, and provides extremely flexible DRFM hardware and ECM emulation processing blocks. The DRFM hardware emulation block allows configurable simulation of specific hardware characteristics such as number of ADC/DAC bits, input and output analog filter emulation, and limits on memory depth. The ECM emulation block allows arbitrary time varying amplitude, delay, and frequency offset profiles to be generated as well as generation of arbitrary bandlimited noise sources. These configurable blocks allow easy simulation of many ECM modes including RGPI/O, VGPI/O and other coherent and non-coherent techniques. The JEM system contains a self-calibrating RF architecture to enable tight amplitude and phase matching between RF channels. The JEM system is configured via an intuitive GUI which allows graphical input of all time varying profiles. The JEM system utilizes a simple ASCII based interface and is readily integrated with existing simulators following the Joint Integrated Mission Model (JIMM).
