干扰源相位对目标体电磁散射特性的影响
Research on the Influence of Interference Source Phase on Electromagnetic Scattering Characteristics of the Target
摘要
Abstract
The electromagnetic scattering characteristics of the target when it is irradiated by radar and interfer-ence source are much more complex than that when it is only irradiated by radar in the complex electromagnetic envi-ronment.The influence of the interference source phase on the electromagnetic scattering characteristics of the target has important practical value for researching electronic countermeasures,the stealth performance of the target,and the accurate detection,tracking,positioning,and identification of the target by radar.This study studies the changes in the electromagnetic scattering characteristics of the target caused by the combined action of radar waves and elec-tromagnetic waves radiated by interference sources.The RCS(Radar Cross Section)of the target varies with the phase difference of the two beams in different directions,and the influence of the interference source phase on the electro-magnetic scattering characteristics of the target is analyzed.The numerical example shows that the RCS changes 10.1 dBsm when the target is affected by the interference source,and the influence on the maximum radar range is 1.34 times.The RCS of the target has a change of 8 dBsm with the change of the phase of the interference source,which has a 0.21 times effect on the maximum range of the radar,indicating that the phase of the interference source has an important effect on the electromagnetic scattering characteristics of the target.关键词
