智能雷激光引信扫描目标的建模与仿真

为研究智能雷激光引信一维距离像的特征,将动力学、运动学原理应用于智能雷子弹药扫描运动的建模中。采用解析几何方法建立了地面背景、干扰物、装甲目标、扫描线与目标交会的数学模型。仿真计算了智能雷激光引信在不同干扰物影响下,扫描静止和运动的装甲目标所产生的一维距离像。结果表明:激光引信能够多次探测目标,探测目标的次数与时间由智能雷子弹药与目标的相对位置决定;对外形特征明显的目标,激光引信一维距离像具有唯一性。建立的仿真模型可为智能雷总体设计、激光引信设计、目标识别算法的研究提供参考和借鉴。

Modeling and Simulation on Scanning Target Using Laser Fuze of Intelligent Mine

In order to study the range profiles of laser fuze installed on intelligent mine,the dynamics, kinematics and analytic geometry are applied in scanning movement modeling of intelligent mine submuni tion. The mathematics models of ground, barriers, armored targets, and rendezvous of scanning line and target are established by using an analytic geometry method. At the same time, the computer numerical simulation of range profiles of laser fuze scanning the stationary and moving armored targets are carried out under the influence of different barriers. The results show that laser fuze could detect target repetitiously, the frequency and time of detecting target depend on the relative position of the mine submunition and target, and the range profiles of laser fuze has uniqueness for the target with unique figuration. The simulation model can provide references for overall design of intelligent mine, design of laser fuze and research on target recognition algorithm.
