摘要
针对常规防空炮弹对付体目标不能设定引信启动区实现精细起爆控制问题,提出了基于频谱特征的引信自适应延时数学模型。数学模型将真实目标处理为体目标,提取无线电引信目标多普勒信号频谱信息,估算弹目交会参数和引信总时延,调整目标尺寸补偿时延,设定引信启动区。仿真结果表明:该数学模型比传统的时域测频定角炸点控制数学模型具有可设定引信启动区的优点,可以实现精细起爆控制,增强了引信与战斗部间的协调性。
Conventional air-defense projectile can＇t set fuze initiation zone to realize fine burst control when attacking bulk targets. To solve this problem, an advanced fuze adaptive delay time mathematics model based on spectrum feature was proposed in this paper. The model treated real targets as bulk targets, extracted spectrum feature of target Doppler signal, estimated encountering parameters and the whole delay time of fuze, and set fuze initiation zone by adjusting size offset delay time. Simulation results showed that the proposed model of setting fuze initiation zone was superior to the fixed angle initiation model based on frequency extracted in time domain, and this model could realize fine burst control and enhance the coordination between fuze and warhead.
