摘要： 研究基于M/N逻辑和基于一步延迟的航迹起始方法，结合两者提出一种新的航迹起始方法。对落入相关区域中的量测加强约束条件，使每一个测量只能在一条航迹中出现；将相邻2个周期的权值与阈值进行比较，减少杂波对起始性能的影响。仿真结果表明，该方法在保证低虚假航迹概率的情况下，能正确起始航迹，缩短航迹起始时间，适用于密集杂波环境下的多目标航迹起始。

Abstract: After a thorough study on M/N Logic-based method and one-step delaying method for track initiation, this paper proposes a novel track initiation method based on the combination of the above two methods. It adds a limitation to the measurement from related district, which relatively simplifies the track initiation. It reduces the influence clutter made on track initiation by comparing weight and threshold from two adjacent periods. This approach can initiate the track properly and shorten the time of initiation at the same time under the guarantee of low false track probability. It is appropriate to the multi-target track initiation under dense clutters. Simulation results testify the validity of the present method.

Key words: track initiation, M/N logic method, one-step delaying method, multi-target track initiation
