Patent number: 9845503Abstract: A nucleic acid tag comprising a nucleotide-support platform attached to a nucleic acid molecule, an odorant, and an encapsulant. Unique nucleic acid-containing tags containing an odorant are seeded at one or more geographic locations. Using odorant-detection systems, the person or object of interest is examined for the presence of one or more of the odorant, thereby revealing the presence of the seeded nucleic acids and eliminating the expense and time associated with unnecessary screening. The geographic location associated with each detected nucleic acid is used to backtrack the item's path or extrapolate a probable point of origin.Type: GrantFiled: April 6, 2016Date of Patent: December 19, 2017Assignee: SRC, Inc.Inventor: Mary F.

Patent number: 9810606Abstract: Various embodiments and implementations herein are directed to an aerosol and vapor sampling device that has a nozzle capable of focusing/concentrating the sampled particles by accelerating them in a narrow jet and driving the particles into an impaction well containing a collection substrate. The aerosolized particles, aerosolized droplets, and chemical vapors are retained by using a porous collection substrate, having substantial depth and mounted on a porous backing, such as a screen. This configuration allows a minor air flow through the collection substrate. This minor flow allows a well impactor to retain intercepted aerosolized particles. It also improves the inlet's ability to collect and retain chemical vapors or liquid aerosol droplets that are partially filtered and captured in the substrate's matrix.Type: GrantFiled: February 1, 2016Date of Patent: November 7, 2017Assignee: SRC, Inc.Inventors: Stephen R. Houghton, Marc P. Roberts, Robert M. Cannon

Patent number: 9772402Abstract: The present invention is directed to a ground moving target (GMTI) radar that can detect targets, including dismounts, with very small minimum detectable velocities by combining signals from antennas on different spatially separated platforms in a main beam clutter-suppressing spatially adaptive process without requiring that the relative positions of the antenna phase centers be accurately tracked. The clutter nulling is in addition to that provided by the Doppler filters. The spatial displacement provides a narrow main beam clutter null reducing undesired target suppression. The clutter-suppressing spatially adaptive structure is used in both the sum and delta channels of the monopulse processor so that the beam distortion caused by the spatial nulling is compensated for, and the monopulse look-up process is preserved to maintain angle accuracy. Noncoherent integration is employed to recover signal to noise loss resulting from the uncertain relative locations of the platforms.Type: GrantFiled: June 9, 2014Date of Patent: September 26, 2017Assignee: SRC, INC.Inventors: Harvey K. Schuman, Ping G. Li

Publication number: 20170102458Abstract: The present invention is directed to a method for processing radar signals in a distributed array radar that includes a first airborne platform and at least one second airborne platform. Doppler filtered radar return samples are obtained and a weight value is calculated as a function of first clutter signals and second clutter signals. The weight value is employed in a weight vector that is computed, as well, from a steering vector that need not be matched to the target vector. The weight vector is applied to a signal vector corresponding to the Doppler filtered radar return samples. An open loop feedback is implemented and configured to create beam pattern nulls at angles corresponding to the plurality of first interference signals within each of the Doppler bins without substantially tracking a position or velocity of the first airborne platform or the at least one second airborne platform.Type: ApplicationFiled: June 9, 2014Publication date: April 13, 2017Applicant: SRC, INC.Inventors: Harvey K.
