针对现有激光主动制导**导引头易受欺骗式干扰的技术现状，提出了采用伪随机序列编码提高其抗干扰性能的新构想。利用伪随机序列抗干扰性能较好的特点，可以使激光主动探测目标系统既能实现远距离主动探测目标，又能有效防止外界干扰，提高系统性能的可靠性。本文结合Arduino IDE、Arduino UNO R3 单片机、示波器与YAG 激光器等实验仪器，设计并实现了一种抗干扰性能良好的伪随机序列激光制导信号产生系统。该系统可以用于新型目标指示器的研究。

In view of the current state of the technology of the laser-guided weapon system that is vulnerable to fraudulent interference, a new idea using random sequence coding is proposed to improve its anti-jamming performance. By using the characteristics of better anti-interference performance of pseudo-random sequence, the laser active detection target system can not only achieve long-distance active target detection, but also effectively prevent external interference and improve the reliability of the system. The signal generation system is designed and implemented by combining Arduino IDE, Arduino UNO R3 microcontrollers, with oscilloscopes and YAG lasers, with good anti-interference performance. The system can be used for the study of new laser target indicators.
