TEST BENCH FOR TESTING AND TUNING RADAR LEVEL METERS Russian patent published in 2007 - IPC G01F25/00 

FIELD: radio engineering; radar quality control.

SUBSTANCE: device has upright 1 bearing level gauge 2 fastened on it, support 3, flat reflector 4 fixed on support 3, horizontal motion device 7 having platform, means 8 for measuring distance (8) from selected reference mark (O) to flat reflector 4, additional reflector 9 and screen 10 manufactured from radioabsorbing material. Support 3 is placed on platform of horizontal motion device 7 for changing distance (8) from a reference mark (O) to flat reflector 4. The screen 10 is mounted on carriage means 11 for horizontally moving it, the carriage being rigidly connected to horizontal motion device 7 via connector 12. Additional reflector 9 having quadric surface shape is mounted on upright 1. To reduce the number of reflections from additional reflector 9, two auxiliary screens as radioabsorbing curtains 14 are introduced. Chambers and their costs at simultaneous reduction of an error of measurements.
