针对传统航迹起始算法在红外凝视跟踪系统应用中存在的弊端，提出了一种适用于凝视跟踪系统的多规则快速航迹起始算法。该方法通过深入分析红外凝视系统中目标自身特点及其运动特性，给出了能够对低速甚至静止的大威胁概率目标和断续点迹目标进行威胁概率判断和航向方差判断的起始规则，实现了凝视系统下对大威胁概率目标和断续点迹目标航迹的快速起始。仿真结果表明该算法能够将虚假航迹起始概率控制在10%以下，并且只需要3至4个采样周期即可准确地起始航迹。同时，实际应用表明了该算法在杂波环境下的有效性和稳健性。

A fast multi-rule track initiation algorithm used in an infrared staring tracking system is proposed to overcome the deficiency of conventional track initiation algorithm. Based on the analysis of the target signatures and its kinematics in the infrared staring system, an initiation rule for determining the threat probability and course variance of low-speed or even static targets with high threat probability or targets with fragmentary plots is put forward, and fast track of these targets in the staring system is initiated. Simulation result indicates that the algorithm controls the probability of false track below 10%, and initiates tracks after only 3 or 4 sampling periods. The validity and robustness of the algorithm is verified in clutter environment.
