WIDE BAND LUNAR RELAY COMMUNICATIONS.
Abstract
This study describes and analyses an approach to the problem of increasing Lunar relay bandwidth. An adaptive receiving array is described which makes possible the use of exceptionally large apertures capable of being focused on a small spot on the Lunar surface. However, an analysis shows that sidelobe effects considerably reduce expected bandwidth gains. A bandwidth of 25 kc is calculated for a 1000 ft square X-band array which employs a ''maximum energy'' taper. Between 256 and 1024 array elements are required. (Author)
