Urban UGS systems will include networks of
leave-behind sensors that provide localized surveillance
supporting Military Operations in Urban Terrain (MOUT). They can
be hand-employed by Soldiers or robotic vehicles either inside or
outside buildings and structures. The Urban UGS include various
Sense Through The Wall (STTW) systems, developed to address
current urban warfare requirements. (STTW) Systems will detect,
locate and “see” personnel hidden behind non-metallic walls, doors
and other visible obstructions. Future capabilities will include
detection of concealed weapons and explosives. Among such systems
is the Enhanced Motion And Ranging System (EMARS) developed by
Raytheon. This sensor uses low frequency radar designed to detect
motion behind walls. The system calculates the range of motion of
up to 16 targets detected in front arc of the sensor. The hand
held unit comprises separate sensor and control unit, enabling
remote monitoring of multiple sensors. A different system is
developed by BAE Systems. This sensor uses a 920MHz CW radar,
detecting motion through walls up to 30 cm thick. Such motion
triggers an alarm sent directly to a pager or PDA. The sensor uses
a directional Yagi antenna or omni-directional whip, used as
"leave behind" Urban/MOUT Advanced Sensor System (UMASS).
