Defense Applications of Innovative Remote Sensing (DAIRS)
Abstract
The Defense Applications of Innovative Remote Sensing (DAIRS) program seeks to enable new approaches for the persistent long-range tracking of maritime and air targets. Specifically, DAIRS will focus on the use of surface wave over-the-horizon radar (SWOTHR) with operation in low latitudes, where spread-Doppler clutter currently limits reliable target track to ranges less than 100km, and the low bandwidth precludes the use of microwave target classification approaches. The program will explore passive remote sensing using endemic noise sources as a highly disruptive method for environmental and target sensing. Space time adaptive processing and polarimetric sensing provide the baseline technologies for clutter rejection and this program will combine those techniques with technologies developed in the Shosty program (budgeted in PE 0603767E, Project SEN-01), which uncovered spatial-temporal correlation that potentially provides suppression of spread-Doppler clutter. The program will develop these methods for various conditions that affect SWOTHR, including the day/night cycle, sea state, forward scatter and backscatter, and bistatic range. Additionally, the program will take a first-principles approach for conducting classification at high frequency wavelengths for total disruption of the field. Technology developed under this program will be transitioned to the Services and the U.S. Coast Guard.
