Distributed Mixed Sensor Aircraft Tracking

A combination of geographically distributed small acoustic arrays and imaging sensors can be used to passively detect and track low-flying aircraft. Lincoln Laboratory has developed detection and tracking algorithms to illustrate this concept and has demonstrated them in real-time using an experimental test bed. This paper describes the algorithms, the test bed system and experimental results. The experiments are believed to represent the first real-time demonstration of a distributed mixed sensor tracking system of this type.
