MULTICHANNEL SCANNING RADIOMETER WITH WIDE SWATH Russian patent published in 2008 - IPC G01J3/06 

FIELD: measuring techniques.

SUBSTANCE: radiometer forms a number of data paths and consists of serially stationed and optically interconnected plane mirror, data optical units, calibration units and video signal processing unit. Emission receivers are electrically connected to the video signal processing unit, switching analogue-digital converter, clocking unit, internal storage device, unit for computing correcting coefficients and offsets and an image data correction unit. The output of the analogue-digital converter is connected to the input of the internal storage device and the input of the correction unit. The clocking unit is electrically connected to the drive unit, line onset sensor, emission receiver, analogue-digital converter, internal storage devices and correction unit. The outputs of the internal storage devices are connected to the unit for computing correction coefficients and offsets, which in turn is connected to the input of the correction unit.

EFFECT: change in background and sensitivity of the optical channel is achieved in each image line.
