The landing navigation system is an important guarantee of flight security for planes. The worsening airport elec?tromagnetic environment has strong impact on the security of planes landing navigation. Taking the instrument landing system as an example,the basic theory of landing navigation system is analyzed,and the mathematic model of planes′received signal during the landing navigation process is provided. Based on this model,an evaluation method of airport electromagnetic environment is proposed. The validity of this method was verified by using computer simulation.
