采用捷联惯导系统的反辐射导弹抗关机制导方案研究

Study of Guidance Scheme with Ability Against Target Radar Switching - Off Based on Strapdown Inertial Navigation System for Antiradiation Missiles

本文提出了一种基于被动雷达导引头＋捷联惯导系统的空地反辐射导弹复合制导方案。在此主制导方案的基础上，设计了“目标视线角优化估计”抗关机制导方案，建立了反辐射导弹抗关机性能评估准则，最后通过数学仿真，验证了本文所述方案的有效性。

A compound guidance scheme based on passive seeker + strapdown inertial guidance system for air - to - ground antiradiation missiles ( AGARM ) has been put forward. On the basis of the main scheme , a guid- ance scheme with ability against target radar switching - off , called LOS angles optimal estimation , has been proposed. Then the criterion evaluating the per- formance of the AGARM against target radar being switched off has been es- tablished. At last , the mathematics simulation has been carried out to prove the effectiveness of the proposed scheme .
