Title: Real-Time RF Channel Impairment Emulator
Agency: DOD
Contract: N66001-12-C-5247
Award Amount: $746,496.00


The Joint Tactical Radio System (JTRS) program has need of a programmable and extensible wireless channel impairment emulator accommodating networks of 8 to 100 radio nodes operating in a frequency range of 2 MHz to 2 GHz. The emulator should be high fidelity, broadband, have good delay and attenuation resolutions, a large dynamic range, low minimum latency, provide high isolation between radios, and emulate propagation delays of up to 1 second. The emulator should handle radio networks using multiple protocols and waveforms, including full duplex, frequency agile, and power adaptable radios, through a single RF port per radio. The emulator should be capable of running programmed scenarios with time-varying losses, delays, multipath, Doppler, and statistical fading. Toyon proposes to meet these requirements with a modular and scalable design that has 400 MHz input, and 250 MHz output bandwidths over 2-2000 MHz while offering a large emulated receive signal dynamic range and high isolation full duplex operation with transmit powers from 1 mW to 200 W. The emulator is waveform agnostic, handles frequency agile radios, and emulates 64 time-varying, high fidelity multipath channels in an eight radio network, with 8 emulation channels reserved for digital links to external emulators.
