摘　　要：以弹目相遇时间及导弹所需法向过载为研究对象,建立了引入附加增量下的比例导引规律数学模型,分析了比例导引系数和附加增量对弹目相遇时间及导弹所需法向过载的影响,并运用Matlab语言进行仿真,仿真结果表明与传统的比例导引法相比,选择合适的附加增量不仅可以缩短弹目相遇时间,还有助于稳定导弹所需法向过载曲线的末端跳动现象。最后就比例系数和增量的选取提出了建议。Take encountering time and overload needed by missile as research object, establishes the math model of proportional guide law based on increment under the condition of leading into additional increment, then analyses the influences which different proportion and increment coefficient bring to encountering time and the overload needed. Using Matlab language to simulate, simulation results show that compared with tradition proportion guide law, select suitable additional increment can reduce encountering time and the pulsate phenomenon at the end of overload needed curve. Finally, puts forward suggestion for how to select proportion and increment.
