Second annual special session on image reconstruction using real data

The second annual AP-S/URSI special session on image reconstruction using real data was held at the 1996 AP-S/URSI International Symposium in Baltimore, Maryland. The participants tested their inversion algorithms on X-band measured data, collected at the USAF Ipswich Measurement Facility. Measurements were made available on a series of complicated objects. Some of the targets were fully known to the participants, while other targets were deliberately presented with a minimum of description: the so-called mystery targets. The targets for 1996 are described with illustrations.
