摘　　要：混沌理论在雷达和通信领域中已成为研究热点。对基于FPGA的混沌脉冲产生技术,从周期性、相关性和平衡性3个方面研究了这种基于有限精度硬件产生的混沌信号的随机性能与数据设置字长、信号长度等因素之间的关系。研究结果表明:基于FPGA产生的混沌信号可以具有很长的周期,同时保持了良好的随机性能。Chaotic theory becomes the hot spot in the field of radar and communications. This paper studies the technology of chaotic pulse generation based on FPGA. From the following aspects such as cycle, correlation and balance, the relationship between the random property of chaotic signal generated by hardware with finite precision, and word length, signal length is studied. The studying results show that the chaotic signal generated by FPGA has a very long cycle and good random property.
