A Low-Power, High Sensitivity, X-Band Rail SAR Imaging System
IEEE Antennas and Propagation Magazine（2008）
摘要
Wideband radar imaging with range gating and high sensitivity can be achieved with the use of low-cost commercially available narrowband IF filters. Such filters reduce the effective receiver noise bandwidth of the radar system. This allows for high sensitivity, comparable to that of single-sideband radio receivers, while at the same time acquiring de-chirped wide-band received waveforms. A carefu...
