| 摘 要： | 双基地多普勒雷达是指将发射机和接收机分置在不同的地点或飞机上的一类雷达系统。该文建立了一类双基地多普勒雷达距离跟踪模型,由于双基地多普勒雷达系统所对应的量测模型具有高度的非线性,从而造成了滤波的困难,为此,该文提出了一种基于粒子滤波的概率数据关联算法用于解决上述困难,通过仿真,在相同的系统模型下将其与传统算法进行比较,证明前者具有更好的非线性滤波性能。 |
| 关 键 词： | 双基地多普勒雷达 粒子滤波 非线性 |

| Abstract: | Bistatic Doppler radar is a type of radar system where transmitter and receiver are deployed in different locations and planes. In this paper, a bistatie Doppler radar range track model is constructed. However, the measure model is a strong nonlinear in bistatic Doppler radar system, which brings troubles in filter. For this, a probability data association algorithm based on particle filter algorithm is presented to solve difficulties mentioned above. Finally, a comparison is made between the new algorithm and PDAF - EKF algorithms under the same system model. The simulation results show that the former have higher accuracy. |
