Following a survey of commercial-off-the-shelf (COTS) un-cooled infrared technology, a micro-bolometer array has been selected to form the basis of a low-cost, compact thermal infrared imager intended for use on an Earth observation micro-satellite. The preliminary instrument concept has been designed to yield a 500 metre ground sample distance over a 150 kilometre swath width, from 710 km altitude. The radiometric performance is expected to yield a NETD less than 1 K for a 300 K ground scene. The imager is designed to be compatible with Surrey’s existing microsatellite imagers, which operate in the visible and near-IR bands. The proposed imaging suite will be suitable for many thermal imaging and hot spot detection mission scenarios. Fabrication and characterization of a 1-3 kg space-ready instrument is planned for late 2004.
