Coherent Distributed Radar for High-Resolution Through-Wall Imaging

Abstract

We continued developing an overall plan for design of RF transceiver hardware for very accurate synchronization. Selection of key hardware components, such as a highly accurate reference clock has been narrowed down a few candidates. A meeting with the ONR client, and SAIC staff to kickoff the project was held. In this report we discuss progress in hardware design, synchronization algorithm, and definition of the final demonstration. In the previous period we had identified a very high accuracy reference clock that has very high cost (approximately $2K), long lead time (approximately 6 months), and is available from only one vendor. In this period we have determined that reference clocks with somewhat higher levels of phase noise may be used without affecting the final synchronization accuracy. We have identified three potential candidate reference clocks and will analyze the data sheets further, perform simulations, and perform bench top measurements on samples to determine which one will be used in our design.
