对集群光电成像传感器的多源协同相干激光干扰机理研究

目前激光干扰基本是一对一干扰模式，随着光电侦察传感器的大量使用，激光干扰急需面向集群目标的多对多干扰手段。立足于解决对集群化光电成像侦察的有效压制干扰问题，文中提出对集群光电成像传感器的多源协同相干激光干扰方法，以视场外散斑相干合成干扰作为多对多干扰实现的基本思路，探讨其相干干扰机理，建模分析双光束相干激光干扰光电传感器作用效果并提出对集群目标的协同干扰模型。仿真结果表明，激光入射角度是激光协同相干干扰的重要影响参数，能够作为干扰站协同部署的依据。同时，基于PSNR与MSE的图像质量评价结果表明，相干叠加干扰与单光束干扰以及非相干叠加干扰相比具有明显优势。

Research on multi-source coherent laser interference mechanism of cluster photoelectric imaging sensors

At present, laser interference is basically a one-to-one interference mode. With the large-scale use of photoelectric reconnaissance sensors, laser interference urgently requires many-to-many interference means for cluster targets. Based on solving the problem of effective suppression of interference in clustered photoelectric detection, a multi-source coordinated coherent laser interference method for cluster photoelectric imaging sensors was proposed, and the basic idea of multi-pair and multi-interference realization was using out-of-field speckle coherent synthetic interference. The coherent interference mechanism was used to model and analyze the effect of two-beam coherent laser interference photoelectric sensor. The simulation results show that the laser incident angle is an important influence parameter of laser coherent interference and can be used as the basis for coordinated deployment of interference stations. At the same time, the image quality evaluation results based on PSNR and MSE show that the coherent superimposed interference has obvious advantages compared with single beam interference and non-coherent superimposed interference.
