| Abstract: |
| Based on trajectory measurement information in coast and reentry for ballistic missile, a primary analytical estimation method is put forward, and furthermore optimization estimation of launch location with trajectory regeneration has been proposed to improve estimation precision. Numerical simulation verification has been carried out, which may have referential value in missile early warning. |
