Problems solved by technology

However, the HIRF environmental data stipulated in the standard comes from a large number of test summaries in European and American countries. The results are mainly based on the HIRF environmental data of the flight routes in the airspace of Europe and the United States. However, the HIRF environmental data of the airspace flight routes in my country is seriously lacking, resulting in the evaluation and assessment of aircraft-level HIRF tests. Disadvantages of incompleteness and difficulty in guaranteeing security systems

Abstract

The invention discloses a system and method for collecting and processing flight route HIRF environmental data. The method includes the following steps of: continuously and rapidly collecting HIRF environmental data at various stages of aircraft operation by adopting small receiving antennae with different frequency bands, processing the collected data by a real-time analysis module built in a signal spectrometer to further perform time-domain continuous sampling and real-time processing on the HIRF environmental data in the frequency band range, obtaining an envelope curve for collecting theHIRF environmental data in a cabin, testing the shielding attenuation characteristics of a testing machine cabin after the testing machine lands, and reversing the true HIRF environmental value of theexternal route of the testing machine according to the envelope curve in the cabin and the shielding attenuation characteristics. According to the method, the independent acquisition of the HIRF environmental data of airspace routes of China can be achieved, the effectiveness of test evaluation can be effectively improved, and meanwhile, the method can be used for data extrapolation processing from low level to high level in aircraft level HIRF tests.

Description

technical field [0001] The invention relates to the technical field of electromagnetic environmental effects, in particular to a system and method for collecting and processing airway HIRF environmental data applied to aircraft-level tests. Background technique [0002] High-intensity radiation field (HIRF) refers to the radiation from high-power transmitters such as radar, radio, navigation, and broadcasting on the ground, ships, offshore platforms, or aircraft. It has the characteristics of wide frequency band, high peak value, and long action time. The electronic equipment in the aircraft system is facing potential electromagnetic damage, which is mainly reflected in the coupling between the external strong electromagnetic field and the electronic system, thus affecting the normal operation of the key / important electronic systems of the aircraft. From the perspective of flight safety, the US Federal Airworthiness Administration (FAA) and the European Joint Airworthiness A...
