Problems solved by technology

[0002] With the digitalization of airborne avionics equipment getting higher and higher, the weather radar used in a certain series of aircraft is changing with each passing day. For a new type of airborne weather radar laboratory, there has been no testing equipment since 2005, and the laboratory is now Some original 270 series weather radar test systems cannot complete the test work of the new series (1400 series) weather radars. At present, in addition to the introduction of foreign advanced avionics comprehensive test systems (which can only be used for functional testing of new weather radar systems test, but unable to test the specific important technical indicators of the weather radar system), there is no special test system for this new type of airborne weather radar in China

Embodiment Construction

[0021] Combine below figure 1 , figure 2 The present invention is described in further detail with the specific embodiment: based on the design concept of advanced technology and easy operation and maintenance, the connection block diagram of the weather radar test system has been designed (see figure 1 ). The test system obtains DC +28V and single-phase AC 115V power from the power supply unit, and is controlled by the insurance, power switch, and indicator light of DC +28V and single-phase AC 115V on the test platform respectively, and then enters the power filter link for filtering processing, and then Input to the transceiver unit, the transceiver unit converts the input DC +28V power into +23V, ±15V, -20.5V, +7.5V low-voltage voltage, and then provides it to the signal processing unit, antenna extension unit, control unit (including The test platform of the radar system also provides multiple test ports, which can be used to test part of the radar information.). The r...

Abstract

The invention belongs to the technical field of aviation testing and particularly relates to a test system for airborne weather radar of an airplane. The test system comprises a power supply unit, a transceiver unit, a testing platform, a control unit, an antenna extension unit, a data acquisition unit, a signal processing unit, a display unit, a synthesis simulator and a power absorption unit, wherein the testing platform is taken as a center to implement connection of sub-units of a weather radar system. The connection between the units of the system is shown as the figure 1. According to the test system, the test work of all kinds of technical indexes of the novel weather radar is implemented.

Description

technical field [0001] The invention belongs to the technical field of aviation testing, in particular to an airborne weather radar testing system. Background technique [0002] With the digitalization of airborne avionics equipment getting higher and higher, the weather radar used in a certain series of aircraft is changing with each passing day. For a new type of airborne weather radar laboratory, there has been no testing equipment since 2005, and the laboratory is now Some original 270 series weather radar test systems cannot complete the test work of the new series (1400 series) weather radars. At present, in addition to the introduction of foreign advanced avionics comprehensive test systems (which can only be used for functional testing of new weather radar systems However, it is impossible to test the specific important technical indicators of the weather radar system), and there is no special test system for this new type of airborne weather radar in China.
