Video-rate Synthetic Aperture Radar (ViSAR)
Abstract
Recent conflicts have demonstrated the need for close air support by precision attack platforms such as the AC-130J or the MH-60 class helicopters in support of ground forces. Under clear conditions, targets are easily-identified and engaged quite effectively, but in degraded environments the atmosphere is not always clear, and inhibits traditional optical sensors. The AC-130J must fly above cloud decks in order to avoid anti-aircraft fire, and this negates optical targeting sensors. Similarly, rotary/wing blades in urban operations generate copious amounts of dust that block circling assets from supplying cover fire for ground forces. The Video-rate Synthetic Aperture Radar (ViSAR) program will develop a real-time spotlight synthetic aperture radar (SAR) imaging sensor that will provide imagery of a region to allow high-resolution fire direction in conditions where optical sensors do not function. Technology from this program is planned to transition to AFSOC.
