... hence this option is discarded in estimating the signal processing gain. The final expression for the signal processing gain of the lag finder is obtained by the use of the earlier result as T s (n) n=n 1,1 T s (n) n / =n ≈ ... of interest, which include the multipath bounces off various other targets and the ground. This is achieved by forming a space fast -time beam in...
