# Multi-Sensor Fusion **Entity class:** Data-fusion method ## Definition **Multi-sensor fusion** combines observations from different sensors, platforms, locations, or modalities to form a more useful estimate than any single stream can provide. The fused product can improve coverage, confidence, classification, tracking, or resilience when sources have different strengths and failure modes. ## Relationships - **downstream functions:** [[wiki/Automated Target Recognition|Automated Target Recognition]], tracking, [[wiki/Pattern Recognition|Pattern Recognition]], and decision support. - **operational loops:** [[wiki/Sensor-to-Shooter Loop|Sensor-to-Shooter Loop]] and [[wiki/Standoff Technology Integration and Demonstration Program|Standoff Technology Integration and Demonstration Program]]. - **collection:** [[collections/Terrorism, Counterterrorism, and the Intelligence Environment|Terrorism, Counterterrorism, and the Intelligence Environment]]. ## Sources / Provenance - [DHS — STIDP Privacy Impact Assessment](https://www.dhs.gov/sites/default/files/publications/privacy-pia-st-stidp.pdf) ## Simple Reminders, Quotations, and Thoughts > "Preference is for lightweight, integrated, and multi-spectral sensor fusion with minimal A-kit impacts and fitting into existing onboard sensors." > **— USSOCOM**, *accessed September 23, 2026, USSOCOM Capability Areas of Interest* [[reminders/Surveillance/Multi-Spectral Sensor Fusion Should Fit Existing Aircraft Sensors by USSOCOM|Multi-Spectral Sensor Fusion Should Fit Existing Aircraft Sensors by USSOCOM]] > "Reduced Operator Workload: Cognitive Decision Assessment and Aiding technologies to automate or reduce crew workloads.
