A data collection system using software defined radios to perform multi-static radar measurements is presented. The basic architecture and operational capabilities of the selected software defined radios (SDRs) are described. Issues associated with device synchronization are discussed, and waveform implementation procedures are also outlined. Finally, results of preliminary experiments are presented, indicating the potential of SDRs for realizing a cost-effective radar system testbed. In particular, it is demonstrated that by rearranging the SDR configuration, it becomes possible to realize various receive array configurations for detection of moving targets.
Signal processing techniques employed by a software-defined radar are presented. First, the radar system is described in brief, illustrating how software-defined radios (SDRs) are leveraged to implement a baseline radar functionality. Next, multiple, required processing steps are presented, showing how target signatures can be extracted from raw radar measurements. All of these techniques are applied to the moving target indication (MTI) problem, and examples of multiple moving target signatures are displayed.
