Radar architecture

The present invention is directed to a radar system that includes an antenna array having a plurality of antenna elements and a plurality of transmit antenna phase centers. A transmitter portion is coupled to the antenna array. The transmitter portion is configured to transmit a plurality of transmit beams characterized by a transmit beam pattern. The transmit beam pattern has a predetermined transmit beamwidth that is a function of the number of orthogonal transmit waveforms. The predetermined transmit beamwidth substantially fills a predetermined angular volume. Each of the plurality of transmit beams includes a corresponding one of the plurality of orthogonal transmit waveforms. Each of the plurality of transmit beams is transmitted by a corresponding one of the plurality of transmit antenna phase centers. The number of orthogonal transmit waveforms is less than the plurality of antenna elements. A receiver portion is also coupled to the antenna array. The receiver portion is configured to extract a plurality of orthogonal receive signal components from a received signal provided by the antenna array. The plurality of orthogonal receive signal components corresponds to the plurality of orthogonal transmit waveforms. A plurality of extracted orthogonal receive signal components are digitally beam formed to implement a virtual antenna array and generate a receive signal having a receive beamwidth. The virtual antenna array includes a plurality of virtual antenna elements greater than the plurality of antenna elements. The receive beamwidth is a function of the plurality of virtual antenna elements.

Image display panel manufacturing method, image display device manufacturing method, and image disiplay device

In the case of filling and setting the liquid powders or the particles in a plurality of cells formed by the partition walls on the substrate, the method includes the steps of: setting a nozzle at an upper portion of a container; setting the substrate, on which the partition walls are arranged, at a lower portion of the container; scattering the liquid powders or the particles dispersed in a gas from the nozzle arranged at the upper portion in the container; and filling the liquid powders or the particles in the cells on the substrate arranged at the lower portion in the container. After this filling, the method further includes: a filling step for filling a predetermined amount of the liquid powders or the particles in spaces constituting the image display cells isolated by the partition walls; a removing step for removing unnecessary liquid powders or unnecessary particles remaining on the partition walls in the filling step; a substrate stacking step for stacking the transparent substrate and the opposed substrate via the partition walls and applying a sealing agent at a peripheral portion of the substrate so as to make an atmosphere between the transparent substrate and the opposed substrate uniform; and an electrode adhering step for connecting a circuit for displaying the image to the electrode so as to form a module.
