Abstract
A coherent radio frequency memory (CRFM) which employs a digital RF memory (DRFM) and a power limiter at its input for limiting the power of the RF input to a relatively constant level over a broad range of such inputs. In addition, a RF noise generating means is coupled to the input of the DRFM at the optimum level for providing random noise for decorrelating spurious outputs of the DRFM.
