Panoramic imaging perimeter sensor design and modeling

This paper describes the conceptual design and preliminary performance modeling of a 360-degree imaging sensor. This sensor combines automatic perimeter intrusion detection with immediate visual assessment and is intended for fast deployment around fixed or temporary high-value assets. The sensor requirements, compiled from various government agencies, are summarized. The design includes longwave infrared and visible linear array technology. An auxiliary millimeter-wave sensing technology is also considered for use during periods of infrared and visible obscuration. The infrared detectors considered for the sensor design are similar to the Standard Advanced Dewar Assembly Types Three A and B (SADA-IIIA/B). An overview of the sensor and processor is highlighted. The infrared performance of this sensor design has been predicted using thermal imaging system models and is described. Future plans for developing a prototype are presented
