Popis: In this paper the author presents a digital correlation design for the radio holography receiver of DATE5 (the 5-m Dome A Terahertz Explorer). Signal digitization is made at the IF outputs of the receiver and correlation is implemented in time domain. A 4-component algorithm for complex correlation is proposed. With this algorithm, the systematic error is much lower and the SNR is expected to have a 3 dB improvement comparing with the previous 3-component algorithm.
