Abstract

After introducing noise radar probing of acoustic delay lines used as passive tags and sensors, we demonstrate the use of non-cooperative radiofrequency signal sources for such purposes in the context of passive radar measurement. A practical demonstration using IEEE 802.11n (WiFi) is given for a sensor operating at 2.42 GHz, solving the regulatory certification issue met when deploying dedicated radiofrequency emitters for short range radar applications. Furthermore, synthetic aperture radar measurement is completed by replacing the single surveillance antenna with a linear uniform array, solving the sensor collision issue when multiple targets are within range of the radar system.
