Abstract :
The probes coupling signal is significant in RCS (Radar Cross Section) measurement and relative near-field imaging, which has effect on imaging result. This paper presents actual near-field measurement for two dimensional imaging. And the defocusing is found with imaging algorithm based on plane-wave spectrum transforming. It is found that the coupling signal and the coupling distance are related with this phenomenon. With our testing, the target can be focused correctly when the coupling distance satisfies specific conditions.
