| 摘 要： | 通过分析载体的典型运动,建立了几种运动的数学模型并用Matlab进行仿真,同时构造了一种C2连续的3次B样条,插值于模拟航迹中各种运动轨迹的转折点,将不同运动的模拟航迹组合起来,从而实现运动状态突变时的航迹平滑过渡;进一步分析了航迹模拟过程中,探测时可能存在的噪声,模拟了探测器的测量信号;仿真结果表明了中文的方法能够较好地模拟目标的实际运动轨迹,具有一定有效性和实用性,为数据处理和融合算法提供了良好的前提.

| Abstract: | To build up several mathematics models of movements and simulate by Matlab,the typical movements of carrier were be studied.Then a novel method of cubic B-spline withC2 continuity was presented.Interpolating different kinds of tracks,the simulating tracks of different movements were integrated and smoothness transitions can be achieved when the carrier's states of movement changed suddenly.Furthermore,by analyzing the possible noises in the measurement,the signal of detector was simulated.The result indicated that the method can be comparatively effective and practical in simulating the carrier's real track of movement. |
