Software defined radio based Synthetic Aperture noise and OFDM (Wi-Fi) RADAR mapping

We demonstrate the use of commercial, off the shelf, emitter and receiver Software Defined Radio hardware for implementing various RADAR schemes allowing for stacking signals with adjacent carrier frequencies and hence improve range resolution well above the intrinsic hardware bandwidth. Sources include the PlutoSDR andWi-Fi dongles. The receiver is a dual channel Ettus Research B210, with one channel collecting the emitted signal and the other channel the received signal, allowing for emission/reception synchronization. We demonstrate synthetic aperture RADAR (SAR) and interferometric SAR (InSAR) with such a setup well suited for short range (<150 m) target mapping in an urban environment.
