Atmospheric Measurements, Modeling, and Applications

PRA is developing a system that measures distortions on signals of opportunity and inverts these measurements to determine the state of the atmosphere that caused the distortions. This technology is being developed for the mitigation of radar propagation errors that occur at low elevation operations. This system will enable radars to detect and track targets at longer range. The system involves solving the stochastic wave equation using real-time estimates of the atmospheric media.

Precision Positioning and Orientation Technology

PRA is developing technologies for the generation of coded fields that enable compatible receivers to determine their own location and orientation and that of their targets. This technology is being developed for guiding smart munitions, significantly reducing the cost of achieving intercept for low-cost proliferated threats. In addition, this technology is being used to track participants in immersive training simulators.

Fast Settling Filter Technologies

PRA is developing an innovative approach to enable Kalman Filters to settle very quickly. Filters of this nature are used in a large number of engineering applications. The primary application of the faster settling filters is to enable shorter intercept timelines.
