摘要

摘要: 激光告警是激光对抗的重要前提和基本手段，如何在复杂背景噪声下识别来袭激光信号，进而准确报警是激光告警面临的首要问题。该文分析了激光告警设备检测概率与信噪比的关系，从关系式可以看出，为了提高激光告警设备的检测概率，需要增加激光信号的信噪比。提出了一种最大信噪比的自适应算法，进行了算法分析，并利用矩阵变换作出了算法简化，从而保证了系统信噪比的最佳化。最后对最佳权向量的求解这个问题，给出了适用于工程化的最佳权向量求解的简单迭代算法。

Abstract: The laser warning is the important precondition and basic measure in laser countermeasure. The first technical problem for the laser warning is how to recognize a targeting laser signal from complex background noise and accurately raise the alarm. The relationship between detection probability of laser warning equipment and signaltonoise ratio is analyzed. It can be seen form the relational expression that, the increase of the signaltonoise ratio of laser signal is a precondition for improving the detection probability. In order to ensure the optimization of the system signaltonoise ratio, an adaptive method was proposed to ensure maximum signaltonoise ratio. The algorithm analysis was carried out and the algorithm simplification was made with the matrix transformation. Finally, a simple iterative algorithm suitable for the optimum weight vector solution is given.
