    Abstract: The embodiments of the present disclosure relate to the technical field of signal processing. Disclosed are a MIMO sensor, a method for determining a direction-of-arrival approximation degree, and a target information matching method. The method for determining the direction-of-arrival approximation degree includes: respectively obtaining receiving vectors of a first target and a second target according to a processing result of a multi-channel echo signal, calculating a correlation coefficient between the receiving vectors of the first target and the second target, and determining a direction-of-arrival approximation degree between the first target and the second target according to the correlation coefficient. By using the method for determining the direction-of-arrival approximation degree, the real-time performance of multi-channel echo signal processing can be improved.

  • Publication number: 20210214325
    Abstract: A process for forming protoanemonin from an amount of levulinic acid or an amount of ?-Angelica lactone using oxidative dehydrogenation. Biomass-derived levulinic acid (LA) is a green platform chemical and, using an oxidative scission pathway can be transformed into cyclic intermediates, namely angelicalactones to form protoanemonin. The oxidative dehydrogenation may be heterogeneously catalyzed in a gas-phase to perform aerobic oxidation using a solid oxide such as vanadium oxide. Protoanemonin is an intriguing polyfunctional molecule that is uniquely suited to bio-based production, and can be synthesized in yields from 50%-75% during periods of transient reactor operation.
