毕业论文的英文摘要，求翻译

把以下这段翻译成英语。
扩频通信技术已经在军事通信、空间探测、卫星侦察等领域具有广泛的应用。随机码设计是扩频通信的关键技术，利用计算机产生的伪随机码是应用在扩频通信系统的主要方式。然而理论已经证明，伪随机码的安全性不高，是容易破译的。
本文提出了一种利用混沌半导体激光器产生的真随机序列作为扩频码的方案，并用Simulink对扩频系统进行了仿真，验证了方案的可行。相比传统的扩频系统，真随机序列作为扩频码，实现了从硬件上对扩频系统的加密。此系统在提高抗干扰能力的同时也增强了保密性。

Answer 1

Spread spectrum communication technology has been in military communication, space exploration, satellite reconnaissance have been widely used. Random yards design is spread spectrum communication. The key technology of using computer generated pseudo-random code is used in the main way of spread spectrum communication systems. Yet theory has proved that the safety of pseudo-random code is not high, is easy to decipher.
This paper puts forward a method of using chaotic semiconductor lasers generate really random sequence as spread-spectrum yards of spread spectrum, and Simulink scheme, system was simulated shows that the project is feasible. Compared with the traditional spread spectrum system, true random sequence as spread-spectrum yards, realizes from hardware to spread spectrum system of encryption. This system in improving also enhance anti-jamming ability of the secrecy.
