1. A system comprising:
- a plurality of two or more different types of perimeter intrusion detection sensors; and
a computer processor communicatively coupled to the plurality of two or more different types of perimeter intrusion detection sensors;
wherein the computer processor is operable to execute a sensor fusion framework that;
receives event data from the plurality of two or more different types of perimeter intrusion detection sensors;
computes a common location and range uncertainty from the plurality of two or more detection sensors;
clusters the event data from the plurality of two or more different types of perimeter intrusion detection sensors;
analyzes the clustered event data based on different sensor performance characteristics;
generates a single alarm from the clustered data when the clustered data indicates a breach of a perimeter associated with the perimeter intrusion detection sensors; and
provides situation awareness based on alarms generated across the perimeter.

Abstract
A system includes perimeter intrusion detection sensors and a computer processor communicatively coupled to the perimeter intrusion detection sensors. The system receives data from the perimeter intrusion detection sensors, fuses the data from the perimeter intrusion detection sensors, and generates a single alarm from the fused data when the fused data indicates a breach of an area associated with the perimeter intrusion detection sensors. A sensor fusion framework for accomplishing these tasks is described.
