## Definition
The **Standoff Technology Integration and Demonstration Program (STIDP)** developed and tested an integrated countermeasure architecture for detecting person-borne, vehicle-borne, and leave-behind explosive threats in unstructured crowds and public venues. Its published architecture combined multiple sensors, person and object tracking, threat prioritization, data fusion, operator interfaces, and a geographic-information-system backbone.
STIDP belongs directly in this collection because it shows the complete preventive-security loop at venue scale: observe moving people and objects, fuse heterogeneous signals, rank threats, allocate additional sensing, support an operator, and mobilize interdiction resources. It is a concrete precursor to present discussions of multimodal observability and person-scale risk inference.
