摘要
减小电子战平台上雷达和干扰机体积、重量、功耗的有效途径是实现雷达和干扰机一体化,即使雷达和干扰机共享硬件平台,发射信号采用同时具有探测定位能力和干扰特性的一体化信号。提出了一种基于单向耦合映象格子构造时空混沌二相序列的方法,分析了时空混沌二相序列的伪随机性能,构造了时空混沌二相序列调制的一体化时空混沌二相编码信号,并分析了该信号的固有分辨能力和干扰性能。分析结果表明,时空混沌二相编码信号可以作为雷达与干扰机一体化信号,并且具有优良的固有分辨能力和遮盖干扰特性。
Radar and jammer integrated on the electronic war platform is an effective method to reduce their volume, weight and power consumption. Radar and jammer use the same hardware and the same signal waveform called integrated signal with locating and jamming characteristic. Here, the method of generating bi-phase sequences of spatiotemporal chaos is presented based on one-way coupled map lattice. Then, on the basis of analyzing the pseudo-random characteristic of bi-phase sequences of spatiotemporal chaos, the integrated bi-phase encoding signal of spatiotemporal chaos is given. Finally, the intrinsic resolution power and jamming characteristic of this integrated signal are analyzed. The analysis results show the bi-phase encoding signal of spatiotemporal chaos is a good signal for integrated radar and jammer and has fine resolution power and jamming characteristics.
