  • Patent number: 11408994
    Abstract: A side-looking High Resolution Wide Swath Synthetic Aperture Radar, HRWS-SAR, system comprising an antenna array and a beamforming network. The antenna array comprises a plurality of antenna elements to transmit and receive electromagnetic waves. The beamforming network includes a plurality of true time delay lines, TTDLs connected to a plurality of phase shifters. Each phase shifter is connected to a respective one of the plurality of antenna elements. The beamforming network engages with the transmit antenna array to transmit the electromagnetic waves by performing beamsteering across a swath using a pulse. The pulse has a chirped waveform and a transmit pulse duration. Beamsteering is performed based on an increasing or decreasing frequency of the chirped waveform over the transmit pulse duration. The beamforming network engages with the antenna array to receive, during a receive time window, echoes corresponding to the electromagnetic waves reflected by or from the swath.

  • Publication number: 20190134931
    Abstract: A processing method and a processing device for lens mold core, the processing method includes steps of: softening a mold core base; surface treating a work surface of the mold core base by lighting; processing the work surface by removing material. When processing the lens mold core with this method, since the mold core base is softened and the work surface is surface treated by lighting, the processing difficulty of the mold core base is decreased, and thus a tool having a smaller radius and a higher feed rate can be adopted for processing. The tool having the smaller tool radius allows a more precise structure, and the higher feed rate imparts the work surface with a smaller roughness, thereby imparting the lens mold core with a higher processing precision.
