Propagation Research Associates, Inc., (PRA) has combined its unique expertise in atmospheric physics and radar signal propagation to develop the Enhanced Tropospheric Effects Compensation (ETEC) System that will compensate for tropospheric bending errors when tracking long-range, low-elevation targets. The ETEC System will provide enhanced performance over existing techniques to permit greater d ...

Propagation Research Associates, Inc., (PRA) proposes to develop radar polarimeter technology that will instantaneously measure the parameters of the Stokes vector or Polarization Scattering Matrix (PSM) of a target without requiring additional antennas or antenna elements in Missile Defense phased-array radars. The term `instantaneous' is used to mean that the parameters of the Stokes vector or ...

Propagation Research Associates (PRA) proposes an innovative system that will correct angle-of-arrival error for radars tracking long range, low elevation targets. The correction improvement will be an order of magnitude improvement over existing model based measurements and will extend time-lines for Ballistic Missile Defense radars. The proposed Enhanced Tropospheric Effects Compensation (ETEC) ...

Special Operations Forces (SOF) require a real time display of appr opriate data to allow the helmsman to access the damage potential to his cargo (equipment/personnel) and support his decision relative to speed and course selection when operating in rough water. Furthermore, maintenance support personnel need quantitative data to support design decisions and maintenance activities. This proposa ...

Phased-array radar employing wideband digital beamforming (DBF) offers the potential for detecting and tracking incoming cruise missiles while defeating electronic countermeasures such as chaff, jamming and anti-reflective coatings. A wide instantaneousradar bandwidth is essential for defeating these threats, resulting in improved range resolution and target signature. Digital beamforming may be u ...

THERE IS A NEED FOR A RAPID, NON-DESTRUCTIVE METHOD TO TEST FOR PROPER STEEL PLACEMENT IN PORTLAND CEMENT PAVEMENTS. ISTHE GOAL OF THIS PROPOSED PROGRAM TO DEMONSTRATE THE FEASIBILITY OF USING SHORT-PULSE, GROUND-PENETRATING RADAR AS A MEANS OF RAPID STEEL LOCATION IN CONCRETE PAVEMENT. A GENERAL BACKGROUND IN GROUND-PENETRATING RADAR THEORY IS PRESENTED. LABORATORY AND FIELD MEASUREMENTS USING A ...

Combustion chemical vapor deposition (CCVD), which was invented by the principal investigator, is a high quality film deposition technique that can inexpensively and quickly apply lead zirconate-titanate (PZT) thin films in a continuos manner. This technology can be used for the production of ferroelectric capacitors. CCVD is low cost, high quality and versatile. It does not require a reaction cha ...

Currently, thermal spray (flame and plasma spray) is the only single step method of applying most metal and non-oxide ceramic coatings to large objects. These coatings are usually of a low quality, and thin films cannot be applied. An in situ deposition technique that inexpensively and easily applies nitrides, carbides and other non-oxide thin or thick films in an environmentally friendly manner i ...
