Abstract :
An ultra-wideband (UWB) microwave imaging radar system with a circularly polarized antenna is presented. The proposed microwave imaging system operated in the full UWB spectrum (3.1 to 10.6GHz). To verify the performance and resolution improvement of our system, two experimental tests were developed. Furthermore a comparison between linear polarization (LP) and circular polarization (CP) was carried out. Using circular polarization has demonstrated to improve the depth resolution of the UWB microwave imaging radar systems. In addition circular polarization provides a good approximation of the shape and size of the objects.
