Abstract

The four element ultra-wideband (UWB) comb taper slot antenna array with 18 cm element spacing is used for receiving the wideband scattering signal. A double ridge wideband antenna is used as the transmitting antenna and the above developed large aperture UWB array is used as the receiving antenna. The transmitting antenna and the receiving antenna are placed close to each other for quasi monostatic radar imaging. The total linear scan length of target is 200 cm. The receiving impulse signal is achieved not only by the measurement but also by the simulation tool of GEMS. The receiving impulse signals at various positions are processed by the delay and sum algorithm. The results of real beam radar imaging from both simulation and experiment are well agreed.
