Emulating Low Probability of Detection Algorithms

Software Defined Radios (SDRs) can be used to create and modify radio waveforms in order to perform research into various wireless network problems. Defence Science and Technology Group (DSTG) has created the Experimental Framework of SDRs (EFOS) incorporating bespoke SDRs communicating with one another through an RF attenuation matrix. The Harlequin scenario planning software is used to create scenarios using a set of units, and then calculate the radio propagation matrix for this network. This matrix is fed into a Radio Frequency (RF) attenuator, which is used to modify the communications between the SDRs, creating a realistic radio environment. EFOS is described and then demonstrated using a Low Probability of Detection (LPD) power control problem on a simple network.
