Signal Correction for Environmental Distortion ("Over the Horizon")

Description:

Software that corrects environmental wavefront distortion such as time-varying phase and amplitude fluctuations across radar apertures using adaptive correction factors. Algorithm applied on a per range gate basis to compensate for propagation path dependent environmental distortion such as scintillation observed by phased array radar.  Algorithm has achieved a reduction in observed S4 index and phase standard deviation on the order of [2,5] while providing an order of magnitude increase in angular resolution and modest increases in array gain.

Security and military operations and GPS applications are the ideal target market. Patent Pending.
