An anti-interfering"cat-eye"target detection method based on intelligent sight

目前的“猫眼”目标激光主动探测系统尽管发射功率大,探测距离远,但普遍存在质量较大、灵活性差的缺点。为增强灵活性,减少作战反应时间,确保对目标发现即摧毁,可在步枪智能瞄具中集成小功率“猫眼”目标主动探测系统,与现有系统形成优势互补。由于智能瞄具搭载了小型激光测距仪及CMOS图像传感器,因此本文根据其硬件特点,设计了一种利用小功率激光器发射伪随机编码激光脉冲序列、CMOS传感器同步采集数据,通过相关运算提取目标信息的抗干扰“猫眼”目标探测方法,并进行了理论分析与实验验证。实验结果表明,该方法具有较强的稳定性和抗干扰能力,能够使智能瞄具在较复杂的背景中发现“猫眼”目标。

Although the current laser active detection system used to find "cat-eye" target has large transmitting power and long detection distance, it generally has the disadvantages of high quality and poor flexibility. In order to enhance flexibility, reduce operational response time and ensure that the target can be destroyed as soon as it is found, a low-power active "cat-eye" detection system can be integrated in the intelligent sight to complement the existing system. Because the intelligent sight is integrated with a small laser rangefinder and CMOS image sensor, according to its hardware characteristics, this paper designs an anti-interference "cat-eye" target detection method, which uses low-power laser to emit pseudo-random coded laser pulse sequence, CMOS sensor to synchronously collect data, and extract target information through correlation operation, and carries out theoretical analysis and experimental verification. The experimental results show that the method has strong stability and anti-interference ability, and can make the intelligent sight find "cat-eye" target in complex background.
