Abstract： To expand scanning area and attack range without changing the inner structure of intelligent warhead, a new arrangement mode of the scanner for intelligent mine is proposed. The required coordinate systems are established firstly on the basis of advanced dynamics principle, and the exterior ballistics equations are deduced. Then the equations of scanning trails are established by the method of space analytic geometry. To get the scanning trails, the differential equations are transformed into discrete simulation model using the algorithm of fourth order Runge-Kutta and then are simulated using Matlab. Compared with the scanning trails obtained by the traditional layout of scanner, the scanning trails obtained by the proposed layout of scanner has larger horizontal range of scanning circle and bigger trarget acquisition probability. Therefore, the new arrangement mode of the scanner for intelligent mine can increase attack range.

摘要：为了在不改变智能雷子雷本体结构的情况下扩大其扫描面积， 进而增大攻击范围， 提出了一种新型扫描器布置方式。 先应用高等动力学原理建立所需的坐标系， 并为获得飞行扫描轨迹， 推导出子雷飞行的六自由度弹道方程。 然后通过空间解析几何方法获得子雷扫描器在地面的扫描轨迹方程。 采用四阶龙格-库塔算法， 将数学模型转换为可仿真的离散模型， 并利用Matlab进行计算机仿真。 最后将新型扫描器布置方式得到的扫描轨迹与传统的布置方式得到的轨迹进行对比。 结果表明， 新轨迹扫描圆的横向幅度和对目标的捕获概率更大， 新型扫描器布置方式能够增大智能雷攻击范围。
