Out-of-Band Dual Frequency Jamming Prediction Model and Experiment for Communication Stations
The communication station will be affected by interference signals of multiple frequency in complex electromagnetic environment.Assuming the interference signal is strong enough
the communication station will be blocked even if the interference signal is out of band
which makes it unable to receive useful signal and lose combat effectiveness.The out-of-band signal needs significant energy to block receiver;so we can use vector superposition method to analyze useful signal and interference signal
from which the interference prediction model can be derived.Conducting dual-frequency interference test by two independent interference transmission system
and the system should be adjusted before the test.Taking error rate to be 0.1 and no link test as the critical interference criterion respectively
and then two independent tests are conducted.The test result shows that the presented model is able to predict whether or not the equipment under test reaches critical interference state
and the prediction error is within 2dB.This model applies to both critical interference criteria.
