针对现有引信定高测距方法在城市、山区等作战环境中应用及弹药发射参数辨识方法的不足,提出基于涡轮发电机的迫击炮弹发射参数辨识定高方法。迫弹发射参数辨识运用引信上已有涡轮发电机作为速度传感器,运用少量极具辨识价值的速度信息开展辨识,涵盖涡轮发电机停转与不停转两种情况。试验表明:基于涡轮发电机的迫弹发射参数辨识方案可行,算法计算量小,易于工程实现,对开展引信弹道辨识定高具有基础性作用。

Altitude determination methods of traditional fuze can't act effectively in the environment such as city or mountainous area. According to ineffectiveness of the launch parameter methods of ammunition, an altitude determination method of trajectory discrimination based on turbine alternator was put forward based on actuality of ammunition and fuze. The launch parameter discrimination of mortar bomb adopts turbine alternator of fuze as velocity sensor, and few special velocity information is used to discriminate launch parameters, two cases are included. The experiment result indicates that the discrimination project of mortar bomb launch parameters is feasible, the calculation workload is small, and it could be achieved easily and lays foundation for altitude determination of fuze.
