Microwave imaging using distributed sensors

In this paper two-dimensional microwave imaging of irregular shaped metal targets is reported and the focus is to obtain the full 2-D geometry of the target. The study includes full 2-D target scanning and the analysis of scattered signal received from the target (echo signal). The proper processing of the echo signal provides the exact target signature. The analysis is carried out in the X-band region for the near-field target imaging. The images obtained provide the complete information of two-dimensional target geometry. At this stage further improvement is required to obtain a clearer target image. The results obtained till now are sufficient for detecting the target geometry and thus may find applications in metal detection and recognition for security purposes.
