Performance of RF mapping using opportunistic distributed devices

The DARPA RadioMap program focuses on large-area near-real-time spectrum situational awareness. The program seeks to make this capability affordable through using opportunistic distributed devices as the sensor network; that is, through adding spectrum measurement functions to devices such as tactical radios and jammers already deployed for other purposes. This paper provides an overview of the approach and the envisioned uses for the RadioMap capability. We present the evaluation methodology developed for the program, which could apply to any distributed Radio Frequency (RF) Mapping system. We report performance observed in the RadioMap phase 2 field trials that occurred September 2014 in Arlington, Virginia.
