Performance of Coherent-on-Receive Synthetic Aperture Side Looking Airborne Radar.

Abstract

The Coast Guard's Oil Slick Detection Side Looking Airborne Radar was modified to add a synthetic aperture mode. The modification used the technologies of real time digital synthetic aperture processing and making the existing magnetron transmitter/receiver unit coherent-on-receive. Improvement in resolution by a factor of ten and imaging of the ocean surface and moving vessels were demonstrated. Synthetic oil slicks, generated using Oleyl alcohol, were detected by the synthetic aperture radar at a range of 25 km under 10 knot wind conditions and at 9 km under 4 knot wind. Comparison imagery was taken by a standard AN/APS-94D. The OSDR provided greater detection ranges of oil, due primarily to the higher sea return of the 8-foot vertically polarized antenna of the OSDR. The AN/APS-94D, with the higher gain 16-foot horizontally polarized antenna, detected vessels at longer ranges. (Author)
