Patents by Inventor DEAN C. SLOCUM

DEAN C. SLOCUM has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10718850
    Abstract: A navigation system for a swarm of guided projectiles, such as cruise missiles, having three or more projectiles launched at a target is provided. The projectiles can be in secure communication with one another and can operate as a single swarm using a fusion of angle of arrival and time difference of arrival of a detected signal to direct the projectiles to a point of impact on a target that is offset from an emitter generating the detected signal. The projectiles can further use knowledge of their relative position to maintain and/or adjust their flight path and/or speed to maintain their course to the point of impact in areas of GPS denial or unavailability.
    Type: Grant

  • Patent number: 10422644
    Abstract: A method for improving target location accuracy in direction finding systems is disclosed. A target search region is identified based on a set of received signals, and the target search region is projected onto the earth's surface. An initial search grid, which is smaller than the target search region, is placed within the target search region. Next, the initial search grid is expanded to a full search grid by using an optimum number of virtual grid points in order to cover the entire target search region. The correlation coefficients at the virtual grid points between the estimated phases of emitted signals and the estimated phases of the received signals are then calculated. A target is designated as being at a location associated with the highest correlation coefficient. At this point, a new travel path can be initiated to engage or avoid the target.
