考虑技战术信息融合的低空目标敌我识别方法OA

To address insufficient reliability of identification of friend or foe(IFF),as well as existing methods'poor adaptability to high-conflict low-altitude battlefield environments,an IFF method for low-altitude targets under the battlefield airspace control system via a multi-dimensional evidence cor-rection and fusion framework is proposed.Initially,tactical information is processed via fuzzy reason-ing and evidence is modified by using the comprehensive conflict coefficient and contraction-expan-sion function to derive tactical identification results using the Dempster-Shafer(D-S)combination rule.Subsequently,technical data is converted into intuitionistic fuzzy numbers.Identification means and detection cycle weights are respectively determined by using AIFS cross-entropy and Pearson correla-tion coefficient.Ultimately,evidences of each means per cycle are optimized via the evidence discount method,with multi-cycle fused results derived using the D-S combination rule.Case studies and com-parisons demonstrate the proposed method effectively resolves the problem of friend-or-foe attribute misjudgment in complex battlefield environments.
