Ultra wide band (UWB) radar holography is a unique technique developed at PNNL for the U. S. Army to obtain nearfield“3-D” images and scattering characteristics of full-size vehicles in the field and at production line facilities. The extremely high-resolution imaging capability of this technique maps a vehicle’s scattering areas and identifies the“hot spots” which dominate the far-field signature to the enemy’s radar receiver. The combination of generating near-field high resolution images and RCS measurements with the same data provides a very efficient LO signature reduction tool for the Army, Air Force and Navy.
