September 16, 2015 - NOAA awards PRA a contract for "Novel Method for Ground-Based GNSS Radio Occultation Measurement".

The National Oceanographic and Atmospheric Administration (NOAA) has awarded PRA a contract to further develop our technology for ground-based radio occultation measurements.

September 3, 2015 - US Army awards PRA a contract for enhanced CFAR performance in clutter technology.

US Army CERDEC has awarded PRA a 2-year contract to investigate the use of our patented technology for enhanced CFAR performance in the presence of clutter and test with a US Army radar.

August 19, 2015 - Success - Another drone shot down!

PRA participated in another successful US Army ARDEC test at Yuma Proving Grounds to shoot down a drone. PRA provided the fire control algorithms for the engagement.

    March 31, 2014 - Major solar flare erupts from the sun.

    March 27, 2014 - PRA is a new member of ACSWA!

    January 2014 - Dr. E. Jeff Holder's book entitled Angle-of-Arrival Estimation Using Radar Interferometry was published by SciTech Publishing in January 2014.

    September 13, 2013 - NOAA selects Propagation Research Associates to develop GPS ionospheric impact products.

    The National Oceanographic and Atmospheric Administration (NOAA) has awarded PRA a contract to develop a nowcast of ionospheric scintillation impacts on GPS users for its Space Weather Prediction Center. This effort extends work started last year and continues PRA's partnership with NASA's Jet Propulsion Laboratory. The approximate contract value is $400K.

    June 18, 2013 - US Air Force selects Propagation Research Associates to further develop a radar for flightline boundary surveillance.

    The U.S. Air Force has announced its intent to award PRA a $750K 2-year contract to further develop a High Range Resolution Radar for a Flightline Boundary Surveillance system. This effort requires the modification of an existing radar sensor's command and control software to create a boundary encompassing a protected zone for identifying a "friend" or an "intruder". The project leverages PRA's experience in radar signal processing and target classification work.

    May 17, 2013 - US Air Force selects Propagation Research Associates to develop GPS processing for ionospheric awareness.

    The US Air Force selected a team headed by PRA, which includes JPL-NASA and support from Rockwell Collins, to develop algorithms for mobile GPS receivers to better monitor the ionosphere. This $150K effort will leverage PRA's extensive experience in GPS signal processing, remote sensing, and ionospheric state estimation.

    May 2, 2013 - US Army competitively selects Propagation Research Associates for a contract for clutter mitigation technology.

    PRA was notified that the U.S. Army intends to award a $150K contract to PRA for the development of clutter mitigation technology. The technology called "Orthogonal Space Projection Processing with Optimized Waveform Selection for Discrete Clutter Mitigation" will enable high speed adaptive cancellation of discrete clutter in radar returns.

    April 30, 2013 - Propagation Research Associates awarded a patent for lightning probability prediction.

    PRA was awarded a patent on a technique to predict the probability of cloud-to-ground lightning strikes. This technology developed by James Stagliano, Ph.D., a senior scientist at PRA, utilizes the capabilities of polarimetric weather radars to estimate the states of water present in cloud formations.

    April 15, 2013 - Propagation Research Associates gives invited talk at Space Weather Workshop 2013.

    At the Space Weather Workshop 2013 hosted by the Space Weather Prediction Center in Boulder Colorado, the Head of the Atmospheric Research Division Dr. Bonnie Valant-Spaight and Sr. Scientist Dr. G. Martin Hall gave an invited talk about prediction of user impacts of ionospheric scintillation on GPS users. This research was supported by an SBIR contract with NOAA.
