A Distributed Measurement Method of Launch Vehicle Electromagnetic Radiation Emission

Abstract

The invention discloses a distributed measurement method for electromagnetic radiation emission of a carrier rocket. By arranging measuring points inside and outside the instrument cabin of the carrier rocket, a distributed measurement method is used to simultaneously obtain the instruments in the process of the carrier rocket model flight in a single model flight process. The electromagnetic radiation emission characteristic data inside and outside the cabin greatly reduces the number of mock-flying procedures, thereby reducing measurement risks and improving measurement accuracy. At the same time, the method of the invention can use the real-time spectrum capture and storage technology to acquire the radiation emission in the flight process of the launch vehicle model, and provide technical support for the electromagnetic compatibility evaluation of the spacecraft.

Description

technical field [0001] The invention relates to a distributed measurement method for launch vehicle electromagnetic radiation emission, belonging to the technical field of electromagnetic compatibility testing. Background technique [0002] With the improvement of the degree of electrification of the launch vehicle, the electrical equipment of each system is installed in a limited space, resulting in a worse electromagnetic environment in the launch vehicle cabin. The increase in product integration and the denseness of transceiver antennas in a limited space make the electromagnetic environment faced by the launch vehicle increasingly complex. Therefore, it is necessary to confirm whether the electric field emission of the internal electrical equipment and cables of the launch vehicle meets the specified limit, so as to provide The successful flight of the launch vehicle provides guarantee. [0003] There are two traditional measurement methods: [0004] (1) Evaluate the ...

Problems solved by technology

The advantage of this method is that it can obtain the radiation emission data of all the electrical equipment of the launch vehicle during the mock-flight process; the disadvantage is that it cannot obtain the electric field radiation inside the instrument cabin. In addition, this method needs to execute multiple mock-flight processes, which is time-consuming and expensive. There are many uncertain factors in the secondary measurement, which have a great impact on the accuracy of the measurement results.
