Abstract: 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.
