The Autonomous Mine Detection Sensor (AMDS) is a program to develop a suite of advanced sensor technology on a vehicular robot (PackBot). These sensors are characterized as having high detection performance and low false alarm rate. The AMDS program is sponsored by the U.S. Army CERDEC RDES Night Vision and Electronic Sensors Directorate (NVESD). The CyTerra Corporation solution to this problem is the combination of a Ground Penetration Radar (GPR) and a Metal Detector (MD) which comprise the AN/PSS-14. This paper presents the CyTerra Corporation concept and includes performance results from early government sponsored tests.
