# Standoff Technology Integration and Demonstration Program **Entity class:** DHS countermeasure-integration and field-demonstration program **Aliases:** STIDP **Sponsor:** [[wiki/Department of Homeland Security Science and Technology Directorate|Department of Homeland Security Science and Technology Directorate]] **As of:** 2026-09-23 ## 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. ## Relationships - **sponsor:** [[wiki/Department of Homeland Security Science and Technology Directorate|Department of Homeland Security Science and Technology Directorate]]. - **technical architecture:** [[wiki/Multi-Sensor Fusion|Multi-Sensor Fusion]], tracking, data fusion, and geospatial decision support. - **distinct demonstration series:** [[wiki/Thunderstorm Technology Demonstration and Experimentation|Thunderstorm Technology Demonstration and Experimentation]]. - **event ecosystem:** [[wiki/Intelligence and Defense Conferences|Intelligence and Defense Conferences]]. - **collection route:** [[collections/Terrorism, Counterterrorism, and the Intelligence Environment|Terrorism, Counterterrorism, and the Intelligence Environment]]. ## Sources / Provenance - [DHS — STIDP Privacy Impact Assessment, October 14, 2010](https://www.dhs.gov/sites/default/files/publications/privacy-pia-st-stidp.pdf) - [Congressional record — DHS test beds and STIDP](https://www.congress.gov/111/chrg/CHRG-111shrg99104394/CHRG-111shrg99104394.pdf)
