Abstract
Sandia National Laboratories designs and builds Synthetic Aperture Radar (SAR) systems capable of forming high-quality exceptionally fine resolution images. Resolutions as fine as 4 inches (10 cm) in both slant range and azimuth are routinely formed in real time on board Sandia’s DeHavilland DHC-6 Twin Otter aircraft using a Ku-band SAR. Resolutions as fine as 6 inches (15 cm) in both slant range and azimuth are routinely formed using an X-band SAR. Careful system design allows high image quality as measured by nearly ideal Impulse Response (IPR) shapes, with typical Multiplicative Noise Ratios (MNR) of better than 20 dB, and a noise equivalent reflectivity usually better than -30 dB. Collection geometries routinely include squint angles 45 degrees both fore and aft of broadside, on either side of the aircraft. This paper offers a collection of high quality images representative of the output of Sandia’s testbed radar. High-quality fine-resolution images of a variety of target scenes will be displayed, with annotation describing relevant image parameters.
