Abstract

The invention is suitable for the field of aviation testing, and provides a multi-unit radio frequency antenna and antenna feeder system standing-wave ratio testing device which comprises an antenna feeder adaptation assembly, a control assembly and a connecting cable. The antenna feeder adapter assembly comprises an external screw inner hole coaxial connector, a radio frequency circuit board, an earphone socket and four ARINC600 SIZE1 radio frequency coaxial adapters; according to the characteristics of the multi-unit radio frequency antenna, a radio frequency switch chip is taken as a core, a peripheral control circuit and a power supply circuit are designed, a correct method for testing the multi-unit antenna and an adaptive device required by the method are provided, the method and the device avoid the use of an incorrect test method from a device end, and the test efficiency is improved. The test data can be accurately and efficiently acquired, the plugging times of the coaxial connector of the test equipment and the tested antenna feeder system are reduced by half, and the service life of the coaxial connector is prolonged under the condition of the same test times.

Description

technical field [0001] The invention belongs to the field of aviation testing, and in particular relates to a standing wave ratio testing device and method of a multi-unit radio frequency antenna and antenna feeder system. Background technique [0002] The aircraft's airborne TCAS (collision avoidance system) is an important navigation warning system related to flight safety. After the ground failure, the aircraft basically cannot be released to continue the flight. After the air failure, it will not only pose a potential threat to itself and the aircraft in the nearby airspace. Increasing the pressure on the commanders of the air traffic control department will often lead to the return and alternate landing of the aircraft, which will cause greater economic losses to the airlines. Therefore, airlines attach great importance to the troubleshooting and prevention of TCAS systems. Or judge and replace the antenna with declining performance in advance. The scientific test metho...
