| Abstract: | There exist two problems in the traditional algorithm of quadrature sampling and pulse compression.One is that the main lobe after pulse compression is not symmetrical in amplitude,the other is that the phase difference between two adjacent peaks is nonlinear. In this paper, the impact of the frequency leak in DFT and the design of pulse compression coefficient are analyzed,and the improved algorithm is designed and simulated. Finally the superiority of the new algorithm over the traditional one is stated with its practical application presented. |
