A Unique Model of RF Radiation for Detecting and Characterizing a Missile Ground Launch

A new, unique, and innovative theoretical model is proposed to provide the MDA with the ability to detect and interpret the RF signature resulting from the interaction of the initial, unsteady rocket plume formation with the surrounding air and launch padduring the initial launch phase. Preliminary calculations indicate that the signature created at the launch site should be detectable several hundred kilometers away. Physical model can be used to detect and characterize missile ground launch; toidentify location of a surface or underground explosion of chemical explosives; to identify location of launch tube from muzzle blast after projectile exit; to identify source of weapons fire, building demolition, land clearance, and mining operations,pyroclastic flows, and underground magma.
