摘要
为了提高雷达系统的性能,克服一维混沌调频信号因相空间结构简单而抗截获能力差的特点,论文提出二维Cat调频信号和三维Henon调频信号这两种高维混沌调频信号,将其应用在雷达中,从不同方面将三维Henon调频信号与二维Cat调频信号进行比较,仿真结果表明,虽然三维Henon调频信号的维数比二维Cat调频信号的高,但是二维Cat调频信号提高了雷达的距离速度分辨率、成像质量、抗干扰能力和抗截获性能。所以并不是混沌信号的维数越高,其越适合作为雷达信号。
In order to improve the performance of radar system, overcome the one-dimensional chaotic FM signaFs poor anti-intercept ability, which due to the one-dimensional chaotic FM signaFs simple phase space structure, the two-dimensional Cat FM signal and three-dimensional Henon FM signal is proposed. They will be applied to radar and different comparisons of two-dimensional Cat FM signal with three-dimensional Henon FM signal is made in the paper . The simulation results show that, although the dimension of the three-dimensional Henon FM signal is higher than that of the two-dimensional Cat FM signal, two-dimensional Cat FM signal improves the radar range and velocity resolution, imaging quality, anti-interference ability and anti-intercept ability. So not the dimension of the chaotic signal is higher, the more suitable it is for the radar signal.
