Abstract:

A forward looking infrared device FLIR operating at 3.5-5 microns was tested for comparison against a previously tested FLIR operating at 9-12 microns. Results from both tests are used to compare operating ranges of the devices in the tropics. Theory suggests an increased detection and recognition range should be possible by using the mid infrared region. A low infrared profile, 110 Coast Guard patrol boat, served as a target for the mid infrared tests. Tests were conducted off the northern coast of San Juan, Puerto Rico, with temperature and relative humidity conditions similar to those experienced during earlier tests of the far infrared camera. The target vessel was consistently detectable at a range of 7 nmi and sometimes detectable at a range of greater than 10 nmi. Previous similar tests with the far infrared camera found typical detection ranges were less than 5 nmi even with large vessels. The low profile target vessel was recognizable classifiable at a range of 3 nmi. Similar recognition tests with the far infrared camera found typical recognition ranges from 1 nmi with small vessels to a maximum of 3 nmi for large vessels. The mid infrared camera outperforms the far infrared cameras in tropical conditions.
