High-precision navigation and position technologies have a significant demand for indoor robot navigation and positioning, production management and other fields. But existing wireless location technologies have low accuracy and other bottleneck problems which unable meet the urgent needs. New technical and theoretical solutions are needed urgently. 60GHz pulse radio, rising in recent years, known by its high temporal resolution and multipath resolution capability, has provided an effective way to solve this problem. This project will study the geometric positioning algorithm suitable for 60GHz pulse radio under the line-of-sight channel, give the position algorithm strategies and the joint position strategies which suit the 60GHz pulse characteristics and the channel characteristics best; Then，it will research the Direct Position Determination based on compressed sensing under 60GHz complex channels, and give the sparse reconfigurable algorithm and construction strategy of three-dimensional space position grid suitable for 60GHz position requirements according to the sparse features of position goals. Besides，it will study 60GHz position pulse design and optimization methods respectively for different positioning scenarios to reveal the intrinsic relationship between position accuracy, pulse waveform, duration and modulation. Finally, it design a number of simulation tests to verify new algorithms and methods. This project is expected to exceed the centimeter-level precision positioning technology bottleneck, lay a solid theoretical foundation for the research and development of the 60GHz pulse position system, and promote the development of high-precision navigation and position technology.
