Abstract:

The basic requirements of Long Path Infrared LOPAIR systems for detecting and warning of the presence of chemical warfare CW agents re discussed. Several varieties of active LOPAIR systems together with their advantages and disadvantages are reviewed. A simplified version of a non-dispersive infrared analyzer which employs a monobeam pneumatic selective detector is described and compared. The results of some successful preliminary tests are presented and discussed. The tests which were over ranges of 4,350 feet and 10,825 feet 0.824 and 2.05 statute miles were made in the presence of atmospheric scintillation and through the exhaust trails of various aircraft. Successful operation through scintillation is essential to LOPAIR systems. Previous tests on other LOPAIR systems showed them to be adversely affected by scintillation. Conclusions on the use of Narrow Absorption infrared NAIR systems are given. Recommendations and conclusions, and possible test procedures for an active LOPAIR system of the monobeam NAIR type are given.
