Abstract:

In this work, we present SDR-ARI - a Software Defined Radio SDR approach to an Angle-of-arrival-assisted Relative Interferometric ARI RADAR transceiver. It has a number of desirable attributes including the ability to reduce the synchronization, network, and hardware requirements when operating as the sole RADAR modality and its ability to augment existing pulsed and CW RADAR algorithms. While, ARI encoding was initially proposed in prior work, no implementation had been completed and only a pure hardware approach to the receiver was reported. We have developed and implemented a software-defined model in Matlab, and have designed, simulated, and implemented an SDR-ARI transceiver utilizing USRP hardware and gnuRadio software. The use of software-defined radio has allowed us to implement ARI in a timely manner. The proposed approach is described and analyzed.
