The U.S. Army Research Laboratorys ARLs Radio Frequency and Electronics Division sponsored and conducted a series of measurements to characterize the millimeter wave MMW signatures of one Soldier carrying a rocket-propelled grenade RPG launcher with grenade at 34 GHz over three depression angles and for three different body postures prone, kneeling, and standing. The measurements were taken by ARL at its outdoor signature research facility at Aberdeen Proving Ground, MD, on 6 through 18 August 2003. A statistical summary of the measurements is presented in this report, along with a full set of radar cross section RCS plots of the measurements for four linear polarization combinations. Measurements of the Soldier holding an RPG launcher show that the mean RCS of the target decreases with decreasing body profile over all depression angles. The mean RCS does not depend on launcher angle or depression angle in most cases. The co-polarized means are much more sensitive than the cross-polarized terms to changes in body posture and launcher angle. The RPG launcher contributes the largest component to the signature.
