As the key problem of multiple target tracking, track initiation technology has received extensive attention and study. The track initiation technology in the real radar system has been already very ripe. But as to dual-band infrared sensor tracking system, the assumption that the target detected probability is 1 may not be true, because each infrared sensor of the different bands demonstrate different measuring characteristics to different targets. So we can’t simply use the distributed track initiation technology...

As the key problem of multiple target tracking, track initiation technology has received extensive attention and study. The track initiation technology in the real radar system has been already very ripe. But as to dual-band infrared sensor tracking system, the assumption that the target detected probability is 1 may not be true, because each infrared sensor of the different bands demonstrate different measuring characteristics to different targets. So we can’t simply use the distributed track initiation technology which is widely used in real radar tracking system without modified. An initiation method is proposed which is suitable for dual-band infrared sensor target tracking system. Theoretic derivation and emulation test has shown that, with light noise and a low detection rate of sensors, this centralized track initiation method performs better than the distributed track initiation method.

航迹起始做为多目标跟踪技术中的关键问题,得到了广泛的重视和研究。雷达跟踪系统的航迹起始技术已经非常成熟、完善了。然而对于双波段红外传感器跟踪系统,由于各个波段的红外传感器对特定的目标表现出不同的检测特性。在研究雷达跟踪系统时采用的目标探测概率趋近1的假设是不成立的。所以,将分布式航迹起始,然后进行航迹互联的方法原封不动的应用到双红外系统中是否可行需要进一步讨论。提出了一种适合于双波段红外传感器的集中式航迹起始方法,理论推导和仿真试验都表明与分布式航迹起始方法相比,在稀疏噪声、传感器探测概率不高的情况下,这种集中式航迹起始方法具有更好的性能。

The operating system of multiradar systems of the type concentrated is stressed to introduce in the article,the operation of multiradar tracking of the type concentrate more intricate than sigle radar but the rule operate of multiradar and single radar is same : the some mark surveyed is first dealt with first.The usual radar-data processing is come to be in progress according to the fan area.The basic thought is to renew the flight path with the first by way of detection Dian fanning the radar of the area mark,and this kind of method does not occur under the status that joins at the radar,and the flight path is come to renew to total data surveyed earliest can used.Radar system operating mechanism includes system operating,noise pattern and processing,joins processing,flight path association and renew,flight path origin.

着重介绍集中式多雷达系统的运行体制,集中式多雷达跟踪系统的运行与单雷达的相比要复杂很多,但是多雷达与单雷达的运行规则是一样的:先探测到的点迹先处理。通常雷达数据处理是按扇区来进行的。最基本的思想是用最先通过扇区的雷达的探测点迹来更新航迹,这种方法在雷达不发生交接的情形下,总能使用最早探测的数据来更新航迹。雷达系统运行机制包括系统运行、杂波图及其处理、交接处理、航迹互联与更新、航迹起始等问题。
