Abstract EN
The development of four-element ultra-wideband (UWB) comb taper slot antenna array with 18 cm element spacing for real beam radar imaging is described.
The four-element UWB array system with optimum element spacing is analyzed by energy pattern.
A wideband double ridge horn antenna is used as the transmitting antenna, the developed large aperture UWB array is used as the receiving antenna.
The transmitting antenna and the receiving antenna are combined with impulse time domain measurement system to achieve real beam radar imaging.
The receiving impulse signals at various positions are processed by the time delay and sum algorithm.
The examples of several aluminum cans have been verified in the resolution and compared with using the UWB array as a receive antenna and the double ridge horn as a transmit antenna in the test setup.
The crossrange resolution of UWB antenna array is better than wideband double ridge horn antenna because the beam width of UWB array is narrower.
