Abstract
Due to the vast application of electromagnetic signals in air operations, these signals are always disrupted by enemy in order to obscure the signals that are used in flight. Avionic deception (MIJI) as subdivision of electronic warfare is used as observation and decision making devices with the aim to attack or obstruct electronic structures and processes such as sensors, communication lines and transmitting sources.
This type of deception is considered as one of the common techniques of air navigation warfare which limits the effective performance of operation in flight at tactical levels and causing disruption in electromagnetic signals.
In this study it has been attempted to explain the recognition and electronic counter measure methods against MIJI phenomenon and present techniques to nullify it by taking advantages of field and documentation methods along with my flight experience as an aviator.
The obtained results of the study and analysis of this phenomenon show that the pilots and aviators must study and review the records of hazardous MIJI before performing missions in specific and dubious regions.
In order to counter with such phenomenon in navigational missions, the pilots must adjust the flight with terrain and charts known as Dead Reckoning (direct navigation) and in unfavorable conditions use the two systems of navigation aid and ground radar stations, and inform the electronic warfare operation center of any suspicious case through filling out the form of MIJI report.
