Description: ：针对正交编码信号已有设计方法计算复杂、编码长度和数量受限等问题，该文利用混沌序列类随机、初值
敏感， 易产生和易使用的特点， 提出应用混沌序列设计随机离散频率编码信号。 在给出编码信号设计方案的基础上，
详细推导此类信号的模糊函数，分析了其距离、多普勒分辨能力，讨论了信号的准正交特性，并比较了不同混沌序
列对信号性能的影响。 理论分析和仿真实验表明， 结合混沌序列的频率编码信号具有优良的模糊函数、 准正交性能，
且信号产生容易，编码长度和数量可以任意设置，可以作为一类有潜力的雷达信号使用- For deficiencies of existing design methods of orthogonal coded signals such as notably computational
complexity, limited coding length and limited signal number, a kind of random discrete frequency coding signal
based on chaotic series is proposed in this paper, considering the attracting characteristics of chaotic series such as
noise like behavior, initial value sensitiveness and easy for generation and use. The time-Doppler ambiguity
function of the designed signal is induced in detail, the range and Doppler resolution are analyzed, and the
pseudo-orthogonal property is discussed in this paper based on the signal coding model. Signal performances are
compared with different chaotic series. The proposed signals present quite good performances in ambiguity
function, pseudo-orthogonal property, easy generation and unlimited coding length and large signals’ number, and
can be applied as a kind of promising radar signals. Platform: |
