Computed 3-D 35-GHz radar images from a proposed forward-looking synthetic aperture radar (SAR) are shown to help evaluate a proposed landing radar that would mount on the front of a helicopter. The radar, which is currently under design at the US Army Combat Capabilities Development Command Army Research Laboratory, would assist landing in degraded visual environments. In particular, 3-D SAR images of three near-ground obstacles an overhead power-line section and a pristine ZSU antiaircraft vehicle, both over flat ground, and a boulder field are created from computed radar data from their models. SAR images of the models shown in a 3-D space are clearly visible, though the power line may only be detected at very limited incidence angles. Boulders over a rough ground were clearly distinct even with a ground roughness characterized by a root-mean-square height of 15 cm with a correlation length of 2 m.
