Study of a millimeter-wave squint indirect holographic algorithm suitable for imaging with large field-of-view
《Chinese Physics B》2014年第2期546-551,共6页高翔 李超 方广有 
Project supported by the National Natural Science Foundation of China (Grant Nos.11174280,60990323,and 60990320);the Knowledge Innovation Program of the Chinese Academy of Sciences (Grant No.YYYJ-1123)
In this paper a millimeter-wave (MMW) squint indirect holographic method is presented, which is suitable for imaging with a large field-of-view. The proposed system employs the squint operation mode to remove the ba...
