COUPLED WAVE SENSOR TECHNOLOGY

Buried line guided radar sensors have been used successfully for a number of years to provide perimeter security for high value resources. This paper introduces a new com- plementary sensor advancement at Computing Devices termed 'coupled wave device tech- nology' (CWD) . It provides many of the in- herent advantages of leakey cable sensors, such as terrain-following and the ability to discriminate between humans and small animals. It also is able to provide a high or wide detection zone, and allows the sen- sor to be mounted aerially and adjacent to a wall or fence. Several alternative sen- sors have been developed which include a single-line sensor, a dual-line hybrid sen- sor that combines the elements of ported coax and CWD technology, and a rapid- deployment portable sensor for temporary or mobile applications. The single-line sen- sor is intended for fence or wall top perimeter protection, and can be used in conjunction with other fence cut-through sensors. The hybrid sensor provides a high covert detection zone, and can be used in either stand-alone or fence-mounted modes. The rapid-deployment sensor can be carried by a single individual and set up in 20 minutes to secure a 100-metre perimeter. A description of the technology, the sensors, and their characteristics is provided.
