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

Embodiment Construction

[0036] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the present invention provides a system for collecting and processing flight route HIRF environmental data, including:

[0038] Small receiving antenna 1, which is responsible for collecting the HIRF environmental data of the whole process of the aircraft's operation at the airport static state, runway takeoff, air route, and flight landing after power failure;

[0039] A signal and spectrum analyzer 2, which is connected to a small receiving antenna 1, is used for continuous sampling in the time domain and real-time data processing of the HIRF environmental data within the frequency range;

[0040] A control computer 3, which is connected to the signal and spectrum analyzer 2, is used for automatic control of signal and spectrum analyzer data reception and processing;

[0041]...

Abstract

The invention discloses a system and method for collecting and processing HIRF environmental data on a flight route. Small receiving antennas of different frequency bands are used to continuously and rapidly collect HIRF environmental data during various stages of aircraft operation. The real-time analysis module conducts continuous sampling and real-time processing of the HIRF environmental data in the frequency range, and obtains the envelope curve of the HIRF environmental data collected in the cabin. The envelope curve and shielding attenuation characteristics of the test machine are reversed back to the true HIRF environment value of the external route of the test machine. The method can realize the independent acquisition of HIRF environmental data of my country's air routes, effectively improve the effectiveness of test evaluation, and 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...
