摘要/Abstract

摘要：

针对雷达多普勒盲区、低检测概率、弱小慢目标等因素导致的航迹破裂问题，提出一种联合雷达与光电设备的破裂航迹关联方法。首先，由于空间坐标变换会导致各传感器的误差分布发生变化，推导雷达与光电设备量测信息的坐标变换误差的均值与协方差矩阵。其次，在所提的多维分配算法中同时考虑航迹运动特性与异源传感器的量测信息，以实现破裂航迹的重新关联。最后，按照破裂航迹关联结果构建状态模型集，并将之带入到异源融合序贯滤波模块，实现重连航迹的跟踪。所提方法能够显著提高航迹的稳定性与跟踪精度。

Abstract:

Aiming at the problems of broken track caused by radar Doppler blind zone, low detection probability, weak and slow target, and other factors, a broken track association method combining radar and photoelectric equipment is proposed. Firstly, the mean and covariance matrix of the coordinate transformation error of radar and photoelectric equipment measurement information after spatial coordinate transformation are derived because of the change of error distribution of each sensor. Secondly, the broken track is re-correlated by means of the motion characteristics of the track and the measurement information of heterologous sensor are both considered in the proposed multidimensional allocation algorithm. Finally, a state model set is constructed based on the association results of the broken track, and is introduced into the heterogeneous fusion sequential filtering module to achieve tracking of reconnection track. The proposed method can significantly improve track stability and tracking accuracy.

Key words: radar, photoelectric equipment, broken track association, measurement error, heterogeneous fusion sequential filtering algorithm
