A Post-mission Assessment Method for the Effectiveness of Externally Guided Information for Fire Units

With the continuous advancement of operational capabilities of next-generation early warning radar equipment, the firepower strike mode based on early warning radar intelligence for external guidance has become increasingly prevalent, which has become the core support for firepower units to carry out precise strike tasks in modern information-based warfare. However, the reliability of external guidance information directly determines the accuracy and combat effectiveness of firepower strikes. At present, firepower units lack systematic reliability assessment methods when receiving such information, making it difficult to meet the needs of actual combat operations. Therefore, carrying out research on related evaluation methods has important military application value. To address this issue, a post-hoc effectiveness assessment method based on the error comparison between ground-truth trajectories and detected radar trajectories is presented in this paper. The proposed method comprehensively incorporates key procedures including data association and fusion, coordinate error transformation, and firepower effectiveness evaluation, optimizes the accuracy of trajectory matching, standardizes the error calculation, and establishes a complete and operable framework for assessing the credibility of external guidance information. Verification through simulation data of multiple typical combat scenarios shows that the proposed method has good feasibility and stability, enabling quantitatively assessment of the post-hoc effectiveness of external guidance information.
