Abstract

The invention discloses a radiosensitivity testing method. The method comprises the steps that S1, three-dimensional simulation model data of a tested object and near-field radiation field intensity distribution data of a radiating antenna are acquired; S2, according to the three-dimensional simulation model data of the tested object and the near-field radiation field intensity distribution data of the radiating antenna, different frequency electromagnetic wave incident field intensity distribution data of the tested object in different testing distances at different positions is obtained; andS3, according to the electromagnetic wave incident field intensity distribution data, 3dB field intensity coverage data and field intensity uniformity data of the radiating antenna are acquired, a sufficient coverage test is performed, testing position data is obtained, and radiosensitivity testing is completed. Through the method, intensity distribution of incident field intensity on surfaces ofobjects in different shapes can be given according to different testing distances and different frequencies, and the field intensity uniformity in a test radiating area can be assessed to guide electromagnetic protection research and development of the tested object.

Description

technical field [0001] The invention relates to the field of radiation testing, in particular to a radiation sensitivity testing method. Background technique [0002] The continuous increase and enhancement of power radiation from ships, ground or airborne radars, communications, radio and television, etc. has already posed a serious threat to the electronic and electrical equipment and systems of the equipment system. The high-intensity radiation field of the external radio frequency environment is an important part of the complex electromagnetic environment, and the development of modern equipment must consider the high-intensity radiation field in the complex electromagnetic environment. In a strong electromagnetic environment, if no countermeasures are taken, the perception of the equipment system will be confused, command coordination will be disordered, and the effectiveness of frequency equipment will be reduced. In order to protect the key systems of system-level eq...
