Survivability Forecasting Method for Typical Communication Equipment Under the In-band Multi-frequency Electromagnetic Environment

In order to improve the survivability of the frequency equipment,we analyzed the survivability under the in-band multi-frequency electromagnetic environment of typical communication equipment.To analyze the in-band interference mechanism,we established two survivability forecasting models based on two different susceptibility parameters.The electromagnetic radiation effects of single-frequency,dual-frequency,and triple-frequency continuous wave in-band were tested,and the radiation effect change rule was studied in the different frequencies and different magnitudes combinations.The results show that the average power determined model results of in-band dual-frequency,and triple-frequency tests are all approximate 1,the amplitude determined model results are different,the dual-frequency tests results are about 1.4,and the tri-frequency tests results are about 1.6.The results demonstrate the electromagnetic radiation effect in-band of the equipment under test is determined by the interference signal average power,and the second model is able to forecast the typical communication equipment survivability effectively under the in-band multi-frequency electromagnetic environment.
