Next: Coherent integration Up: Astrometry data reduction Previous: Introduction Contents . ... In order to increase the SNR for these data, we coherently integrate the complex visibility for typically 200 ms. The coherent integration is done using the COBRA procedure cohstrictor . In order to provide the necessary input file for this step, the following CONSTRICTOR parameters should be used. ... The .coh extension is standard for coherent integration. ... NumAv = 100. ... Pass on metrology data . ...

... The project assumes creation of an international space observatory - the interferometer "Earth - Space - Space" in order to perform of astronomical investigations in millimeter, submillimeter and infrared regions with extremely high sensitivity (to a few nanoJanskies units of flux density in continuum spectrum) and extremely high angular resolution (to a parts of microsecond of arc or, possibly, nanosecond). ... radio-interferometric channels of the system "Space - Space", region 0.2 - 3 mm; . ...

... Measurements from a pier, platform or a ship in microwave bands (3.6 to 90 GHz) and at thermal IR frequencies to study the sea surface parameters and the ocean-atmosphere interaction. ... Radiometric complex Traverse consists of a set of microwave and IR radiometers, mounted on a automatic rotating platform. ... Since 1999, the complex is used in a series of field experiments on sea surface remote sensing from a pier in Gelendzhik and a platform in Katsiveli (Black Sea). ... Comp
