Patent number: 10120039Abstract: A system for magnetic detection includes a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers, a magnetic field generator that generates a magnetic field that is applied to the NV diamond material, a radio frequency (RF) excitation source that provides RF excitation to the NV diamond material, an optical excitation source that provides optical excitation to the NV diamond material, an optical detector that receives an optical signal emitted by the NV diamond material, and a controller. The controller is configured to compute a total incident magnetic field at the NV diamond material based on the optical signal emitted by the NV diamond material, and drive the magnetic field generator to generate a compensatory magnetic field, the generated compensatory magnetic field being set to offset a shift in the optical signal emitted by the NV diamond material caused by an external magnetic field.Type: GrantFiled: January 21, 2016Date of Patent: November 6, 2018Assignee: LOCKHEED MARTIN CORPORATIONInventors: John B.

Patent number: 8094063Abstract: A method and system for enhancing a radar image provides for application of digital imaging processing techniques to a range-Doppler image produced by a radar system. The application of digital processing techniques includes a 2-D band-pass filter including a smoothing filter followed by a differentiating filter applied to the image. A constraint on concavity is placed upon the resultant 2-D band-pass filtered image to create a mask. The application of this mask to the original image results in an enhanced range-Doppler image with increased resolution.Type: GrantFiled: June 3, 2009Date of Patent: January 10, 2012Assignee: Lockheed Martin CorporationInventor: Jeff D.

Patent number: 8044846Abstract: A method for displaying information relating to the range and Doppler of a remote target includes transmitting electromagnetic energy toward the target, and receiving reflected signals defining a two-dimensional (range-Doppler) radar image. The reflected signals are matched-filtered, which tends to blur the image. The image is deblurred while the features of thermal noise enhancement and irregularity of the deconvolved output are constrained to produce a single point deblurring output.Type: GrantFiled: November 29, 2007Date of Patent: October 25, 2011Assignee: Lockheed Martin CorporationInventors: Harry Urkowitz, Jeff D.
