  • Publication number: 20230075523
    Abstract: Systems and methods for operating a phased array are described. In an example, a system may convert a desired beam direction of a desired beam into at least one phase slope parameter. The phased array may include a plurality of antennas connected to a plurality of front-end circuits of a beam forming circuit, and each antenna may be connected to a respective front-end circuit. For each antenna among the plurality of antennas, the system may determine a phase shift parameter of the antenna based on the at least one phase slope parameter and a physical location of the antenna. For each antenna among the plurality of antennas, the system may map the determined phase shift parameter of the antenna to control settings for a front-end circuit connected to the antenna.

  • Patent number: 11271301
    Abstract: While a radar waveform generator coupled to a phased antenna array is inactive, a beam steering command is provided to the phased antenna array to cause the phased antenna array be configured for a given transmit and receive direction. While the radar waveform generator is active, received radar results are assigned to the given transmit and receive direction. the providing of the command and the assigning are repeated for a plurality of additional transmit and receive directions corresponding to a desired scan area.

  • Patent number: 5821713
    Abstract: An improved commutation position detection system for accurately determining commutation position within polyphase brushless motors without employing proximity sensors or transducers. The present invention determines commutation position. by differentiating the current flowing within the stator coils and comparing the differentiated current waveforms to one another (absolute commutation position detection) or a predetermined threshold (incremental commutation position detection) to obtain a real-time assessment of commutation position.
