| Abstract: |
| After making a comparison between two schemes of mainlobe clutter tracking system in AMTI radar,the paper expounds the principle of a zero-beat frequency discriminating system with high stability of zero deviation point.The essentials of designing circuits and the methods of decreasing the drift of zero deviation point are introduced.The achievement in the scientific research using the system is given. |
