SUBSURFACE DETECTION OF A BURIED OBJECT USING ANGULAR-CORRELATION FUNCTION MEASUREMENT

A new technique is proposed for subsurface detection of buried objects using the angular correlation function (ACF) measurement of scattered waves. Compared with the traditional detection technique which relies on radar cross section (intensity) measurement, this new ACE-based te chnique results in better signal-to-clutter ratio and thus higher targ et visibility. Laboratory experiments were conducted at millimetre-wav e (80-105 GHz) and X-band (7-13 GHz) frequencies to illustrate the pot ential effectiveness of this new correlation approach over the traditi onal cross section approach.
