A real-time close-range imaging system with fixed antennas

A coherent system with two stepped frequency radar sensors separated by 1-2 m is presented in this paper for close-range imaging. Resolution is achieved via range resolution from the two different sensor positions, exploiting both monostatic and bistatic responses. A first test had been performed using a vector measurement equipment for an antenna measurement range as a radar simulator, and a mobile experimental system was built and tested, which included stationary and mobile targets.
