| Abstract: | A new intra-pulse parameter estimation of LFM signal based on FRFT is proposed in this paper to meet the need of accurate measurement of intra-pulse parameter in the target training simulator system. And the calculation process of intra-pulse parameter in the system is also presented. The analysis of the SNR about the performance of the estimation is showed by the simulation. The result shows that the algorithm can provide a high accurate parameter estimation of different LFM signal on the condition of low SNR. |
