Intrinsically Interference And Jamming-Resistant High Frequency (HF) Radios

The Army is seeking through this STTR program to develop high-dynamic-range, high-power-handling, and high-survivability high frequency (HF) radio receivers with significant enhancement in intrinsic interference and jamming resistance.  GIRD Systems is addressing this need with a novel interference mitigation (IM) technology which is inherently a wideband active device that 1) limits input power to the receiver, and 2) reduces or eliminates RFI power in the communication band. The device can perform IM on continuous wave (CW), frequency modulation (FM), and phase modulation (PM) interference, as well as mitigate interference in adjacent channels and even on interference spectra that completely overlap the signal of interest (SOI).  It exhibits sub-nanosecond latency, zero tracking error with respect to frequency or phase, and zero tuning time between frequencies within the band of operation.
