  • Publication number: 20220349989
    Abstract: A wideband direction finding (WBDF) aperture employs a limited number of extreme wideband end-fire antenna elements capable of covering a wide frequency bandwidth. Arranging variable sized antenna elements in a specific pattern, the WBDF aperture enables direction finding capability covering an extreme wide frequency band. The pattern arrangement of variable sized elements offers the signal discernment to limit ambiguities in signal angle of arrival. This small form factor design enables the WBDF aperture to be mounted on the surface of a missile, munition, or small UAS wing or fuselage. The WBDF aperture offers a combination of differing sized antenna elements arranged in a specific pattern, combined with direction finding and signal tracking to provide an unambiguous relative azimuth and elevation angle of the target.

  • Patent number: 10677953
    Abstract: A system for magnetic detection includes a magneto-optical defect center material including at least one magneto-optical defect center that emits an optical signal when excited by an excitation light; a radio frequency (RF) exciter system configured to provide RF excitation to the magneto-optical defect center material; an optical light source configured to direct the excitation light to the magneto-optical defect center material; and an optical detector configured to receive the optical signal emitted by the magneto-optical defect center material.

  • Publication number: 20190285706
    Abstract: A system for magnetic detection includes a magneto-optical defect center sensor and an analytics system. The magneto-optical defect center sensor has a magneto-optical defect center material comprising at least one magneto-optical defect center that emits an optical signal when excited by an excitation light. The analytics system can be configured to receive a measured magnetic field measured by the magneto-optical defect center sensor and identify a device generating at least a portion of the measured magnetic field based on a plurality of nominal magnetic signatures. In some instances, the analytics system can determine a failure of a component of a device or output data indicative of performance of the device. In some instances, the measured magnetic field can be a vector.

  • Publication number: 20190017826
    Abstract: Some precision guidance systems and methods for detecting the position and orientation of one or more magnetic sources are disclosed. The precision guidance system can include a magneto-optical defect center sensor and a controller. The controller can be configured to detect one or more axial components of a magnetic source. Each of the one or more axial components can have a unique, predetermined magnetic signature. The controller can determine a position and orientation of the magnetic source based on the one or more axial components and output the determined position and orientation of the magnetic source to a guidance system.

  • Publication number: 20110007157
    Abstract: A system for providing mechanical stabilization with automated corrections for stationary or mobile surveillance platforms comprises: a telescoping mast that supports a sensor package containing a camera, surveillance radar, a pan tilt unit, and a tilt sensor with a precision compass. Stabilization involves hardware and software enhancements to conventional surveillance systems. Mast stabilization is achieved by a mechanical guy-wire arrangement which provides for both anti-twist and anti-sway support of the mast upper end through a crisscrossed guy wire arrangement. Eight different software algorithms contribute to stability and highly accurate and rapid slewing of the surveillance equipment. A mast tilt calibration algorithm in combination with a calibration sensor package provides for automatic electronic leveling of the camera with dwells at predetermined pan angles.
