摘要
介绍了在红外/毫米波复合制导中观测方程的非线性而产生的跟踪问题,将粒子滤波应用于这一工程领域,并针对其易发生粒子退化现象这一缺点进行了改进,获得了很好的效果,仿真结果证明,粒子滤波较扩展卡尔曼滤波具有更好的跟踪效果,并且由于其并行处理的特性,在工程上有较高的应用价值。
Introduces the problem of tracking using IR/MMW multiple sensors. As is well known, the estimation equations are always nonlinear in this field. Applies the particle filter to solve this problem, the result turned to be good, and particle filter performed better than EKF. The parallel character of particle filter makes it possible to be used in practice by DSP.
