Air line having replaceable joints and used for time delay parameter quantity transmission

Abstract

The invention discloses an air line having replaceable joints and used for time delay parameter quantity transmission. Two ends of an air line outer conductor (1) are respectively provided with an N positive joint, an N negative joint and a plain joint for the replacing of different joint types; the N positive joint, the N negative joint and the plain joint are respectively provided with a first combination of an air line central conductor (2) and any one of an N positive joint central conductor (4), an N negative joint central conductor (7) and a plain joint central conductor (9), and a second combination of the air line outer conductor and any one of an N positive joint outer conductor (3), an N negative joint outer conductor (6) and a plain joint outer conductor (8), wherein of the first combination can be in different connection types and is a time delay value transmission air line. According to the invention, air lines of different connection types, for time delay parameter quantity transmission, can be combined, and accurate and stable signal transmission time delay standard values can be provided; the index test of time delay parameters in different systems can be completed; and problems of a signal channel generated in time delay index check and enclosed ring check of time delay indexes under actual working signals are solved.

Description

technical field [0001] The invention relates to an air line mainly used in the field of radio metering and satellite measurement and control, which adopts replaceable joints to transmit the time delay parameter value, realizes the test of engineering time delay index parameters, and is used for the traceability and measurement of time delay parameters. pass. It can be considered that the present invention can be used not only for closed-loop testing of delay parameters in measurement and control systems in the electronic field, but also for transmission of delay parameters, which can be used as phase and distance standards. Background technique [0002] At present, in the fields of navigation and positioning, high-precision earth observation, etc., the accuracy of the measurement and calibration of the electrical delay time of radio frequency microwave signals often determines the key indicators of electronic information systems, such as positioning accuracy. In actual meas...
