Abstract: A gas filter correlation radiometer mounted on an aircraft is flown over a target area. The gas filter correlation radiometer is configured to detect ethane (C2H6) gas in the event of a gas leak. The gas filter correlation radiometer uses background radiation to detect ethane.

Abstract: A method of detecting a target gas includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of the target gas in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.

Abstract: Un radiómetro (201) de correlación con filtro de gas que comprende: un receptáculo (200) que tiene una ventana (203); una sección del detector montada en el receptáculo (200); ópticas que definen una primera trayectoria óptica (210) y una segunda trayectoria óptica (212) entre la ventana (203) y la sección del detector montada en el receptáculo (200); la primera trayectoria óptica (210) presenta una primera longitud de trayectoria de gas y la segunda trayectoria óptica (212) presenta una segunda longitud de trayectoria de gas, siendo la primera longitud de trayectoria de gas diferente de la segunda longitud de trayectoria de gas; y componentes electrónicos para procesar las señales producidas por la sección del detector como resultado de la radiación dirigida por las ópticas sobre la sección del detector; caracterizado porque el radiómetro (201) de correlación con filtro de gas comprende además: un dispositivo de división de haz de bi-prisma (206, 207) montado en un receptáculo (200) como parte de las ópticas para dirigir la radiación que entra por la ventana (203) procedente de una fuente exterior a lo largo de dos trayectorias divergentes compensadas una con respecto a otra a través de un bi-prisma (206, 207) para dividir la radiación entre la primera trayectoria óptica (210) y la segunda trayectoria óptica (212).

Abstract: A gas filter correlation radiometer mounted on an aircraft is flown over a target area. The gas filter correlation radiometer is configured to detect a gas in a vapour plume in the event of a liquid leak. The gas filter correlation radiometer uses a gas in the vapour or a gas that has a spectral band overlapping a spectral band of the vapour. The gas filter correlation radiometer uses background radiation to detect the vapour.

Abstract: A gas filter correlation radiometer mounted on an aircraft is flown over a target area. The gas filter correlation radiometer is configured to detect ethane (C2H6) gas in the event of a gas leak. The gas filter correlation radiometer may use an ethane peak at 3000 cm-1 to detec ethane. The gas filter correlation radiometer uses background radiation to detect ethane. The gas filter correlation radiometer splits incoming radiation into two paths with different ethane path lengths, detectors on each path having corresponding pixels having collocated fields of view, the corresponding pixels being sampled simultaneously to detect ethane.
