摘　　要：目标空间状态随时间呈现的分布特性被称为目标的时间谱,利用目标的时间谱信息(目标的航迹、速度、机动性、空间坐标信息)可以提高舰艇对空中目标威胁评估的准确性。采用主客观结合的方法对空中目标的状态进行判断达到威胁排序的目的。算例表明,通过时间谱信息进行主客观相结合的舰艇防空威胁评估能够合理利用侦察信息,为舰艇指挥员及时决策提供一个有效的辅助手段。The distribution characteristic of the target spatial state changing with the time is defined as the time spectrum of the target. By using the time spectrum information of the target, including its trajectory, speed, maneuverability, and the space coordinate information, the accuracy of ship to air target threat assessment can be improved. In this paper, the objective approach is used together with the subjective one to judge the state of the aerial targets and achieve the purpose of threat sequencing. Examples show that, the proposed method for warship air defense threat assessment can make reasonable use of reconnaissance information, and provide an effective assistant means to the naval commanders for making decision timely.
