Problems solved by technology

[0004] The invention provides a full-band microwave conversion system for airborne radome electrical performance testing, which realizes the conversion of multi-channel microwave signals into a single channel for receiving and collecting processing, and solves the electrical performance of radar radome of multi-band array antenna and multi-beam antenna The problem that the frequency band channel cannot be automatically switched during the test, in order to realize the automatic switching between the frequency band channel of the multi-band array antenna and the multi-beam antenna during the test, reduce the frequency of manual intervention, and improve the operation efficiency, especially for the test of the phase project, it can ensure Test the consistency of the cable status before and after adding the cover to reduce the impact of the change of the cable status on the test results and improve the accuracy and reliability of the test data

Embodiment Construction

[0031] In conjunction with the accompanying drawings, a full-band microwave signal conversion system for an airborne radome of the present invention is described in detail:

[0032] Including a number of custom-made receiving radio frequency cables. The custom-made radio frequency cables have small loss and low standing wave ratio, which can effectively reduce the change of the amplitude and phase of radio frequency signals. The custom-made cables connect the receiving antenna components with the microwave signal switching unit; to achieve multi-channel reception , the switching unit is composed of three single-pole six-throw (SP6T) coaxial RF switches cascaded and combined. The cascade is realized by semi-rigid ) coaxial radio frequency switch as the primary output, 2 of the 6 routes are cascaded with the remaining 2 single-pole six-throw coaxial radio frequency switches as the secondary output, so that the 16-channel multi-beam receiving antenna can be controlled and received...

Abstract

The invention belongs to the field of aviation technology, and provides a full-band microwave conversion system for testing the electrical performance of an airborne radome, comprising: a control computer (1), a switching unit driver (2), a switching unit (3), and a receiving unit (4); The control computer (1) collects the microwave signal of the receiving unit (4), and sends a channel switching instruction to the switching unit driver (2); the switching unit driver (2) provides the working power for the switching unit (3), and according to the The channel switching instruction controls the switching unit (3) to switch the communication link; the receiving unit (4) receives the microwave signal transmitted by the communication link of the switching unit (3).

Description

technical field [0001] The invention belongs to the technical field of aviation and relates to a microwave signal switching transmission used for airborne radome testing. Background technique [0002] The full-band microwave conversion system for radome electrical performance testing is mainly used for lossless or small loss transmission, reception and acquisition of multi-channel receiving antenna signals in airborne radome testing tasks, including microwave switching drivers and microwave switching parts, radio frequency connectors, control Four parts of the software. At present, there is no corresponding test conversion device, and it is impossible to complete the multi-channel reception, acquisition and processing of radio frequency signals. Contents of the invention [0003] Technical issues resolved [0004] The invention provides a full-band microwave conversion system for airborne radome electrical performance testing, which realizes the conversion of multi-chann...
