Study on Composite Electromagnetic Scattering Characteristics of Air-Floating Corner Reflector and Chaff

Aiming at the problem of single chaff interference against the anti-ship missile with advanced recognition capability, the basic theory of composite electromagnetic scattering characteristic of air-floating and chaff is studied; Through C4D four-dimensional modeling software and CST electromagnetic simulation analysis software, the electromagnetic scattering characteristics of air-floating corner reflector and chaff including radar cross section, high resolution range profile and polarization angle is theoretically analyzed. The coherent synthesis under high frequency conditions is completed by the scattering center synthesis theory; Based on similarity between the electromagnetic scattering characteristics of composite target and typical ship target under dilute interference, optimized laying pattern of composite target is proposed. The results show that the similarity between the air-floating corner reflector/chaff and typical ship target is overall high under the similarity function. The combination use of the two types of passive interference devices has great potential in confrontation with anti-ship missiles with advanced recognition capability.
