The possible harm of high intensity radiated field (HIRF) to airborne decoy in complex electromagnetic environment is analyzed. Through experiment verification, the sensitive frequency of the airborne decoy under HIRF environment is a single and fixed frequency. And the influence of HIRF on the safety of the airborne decoy under the condition of electrification and non-electrification of the dispensing equipment circuit is verified by experiments. Several measures to improve the safety of the airborne decoy are put forward.
