【 摘 要 】

The long-range early warning radar is the key equipment in the early defense process of ballistic missile. For the problem of low working efficiency of long-range early warning radar without guidance information, this paper studies the working process of long-range early warning radar with space-based guidance information, and proposed a new long-range warning radar working mode. Firstly, the coordinate system transformation and guidance information extraction of space-based guidance information are given. Then the concept of coherent accumulation of radar signals is introduced and a new radar operation mode is proposed. Finally, the radar signal coherent accumulation process is established. A mathematical model of radar search distance and intercept probability. The typical scene is built and simulated. The results show that the proposed radar working mode will effectively reduce the search airspace of the long-range early warning radar and improve the radar detection range.
