Abstract
Detection of objects such as a buried explosive device while operating from a moving platform using a radio frequency emission system having two modes. An electromagnetic wave emission and detection system operates in a first mode to locate objects of interest and in a second mode to determine if an object contains explosive materials. In the first mode, the emission and detection system preferably operates as a subwavelength focusing, wideband, superlens using a near field super gain synthetic aperture continuous wave (CW) swept radar. In the second mode the system preferably enabled after detection of an object in the first mode, uses chemical detection methods such as Nuclear Quadrupole Resonance (NQR).
