| () |
| Abstract: |
| The generating theoryof Local coherence is analysed in this paper, also the mathe-matic formula of measring Local coherence is deduced, various kinds of factors that affect Lo-cal coherence are discussed. In accordance with the main factors that affect local coherence,one kind of phase and frequency memory loop is presented for improving the technique of lo-cal coherence, so that the local coherent radar could have the performance of quasi-coher-ence, and the MTI of local coherent radar can be improved evidently. |
