micro-Doppler characteristics analysis of streamlined ballistic target

What is it about?

Micro-Doppler (mD) characteristics of the ballistic targets have attracted great attention due to the potential in target discrimination. However, current investigations mainly focus on blunt-nosed cone and cone-cylinder shaped targets. In practical applications, ballistic targets are always designed as the streamlined shape due to smaller aerodynamic resistance and lower detectability. In this letter, the mD characteristics of streamlined ballistic targets are analyzed. Due to the unique mD signatures, the sliding scattering center induced by the reflection from the streamlined curved-surface is particularly focused. Finally, simulation results via electromagnetic computation verify the correctness of the analysis.

Why is it important?

In my opinion, the streamlined structure is almost applied in the actual ballistic target design.
