Abstract

Remote detection and characterization of wireless devices in an environment is a topic of growing importance. Characterization of a wireless device is useful in many applications. An example of this is in the testing of FCC Part 15 devices. These devices must adhere to strict guidelines in regards to RF interference. Compliance can be verified by using forensic techniques to classify and characterize the returned signal. We present a framework for remote detection and forensic characterization of RF devices using specially designed probe signals. This framework can be applied to a broad range of devices and models. Probe signals, device models, feature selection, classifier design are described. For the device model we introduce a method for simulating a non-linearity in the RF system based on a known diode model. Experimental results are given to verify our approach.
