Methods of Improving Setup Accuracy of Radar Reconnaissance Equipment Database in Complex EM Circumstance

In complex electromagnetic(EM) circumstance,whether radar reconnaissance equipment can alarm to radar signals precisely depends on the judgment of radar reconnaissance equipment to radar signals and the signal parameter setup accuracy of radar database.This paper analyzes some factors that influences the tolerance setup of radar reconnaissance equipment database,puts forward several methods to improve the setup accuracy of radar reconnaissance equipment database to ensure the right sorting and identification to radar signals for the radar reconnaissance equipment,which is the key element to alarm to radar signals.
