In the information age, radar and jammer play important roles in electronic warfare systems. Radar can be used to detect the target preparation, positioning and tracking, Jammer can be used to block and destroy the opponent's use of the electromagnetic spectrum to ensure the security of own information. Radar / Jammer integration system is established by the hardware sharing of Radar and Jammer to reduce the volume of electronic warfare equipment, weight and power consumption. In order to achieve signa(lenergy)share of radar and jammer integration system, launch interference signals is used to interfere radar, but also as a detection signal to detect and combat targets, which the signal is of two kinds applications of radar and jammer, design of integrated share signal waveform is a key issue.The feasibility and efficiency of energy sharing of radar and jammer integrated system design is analyzed and verified in this paper, by focusing on exploring share signal waveform design, through system model and Matlab simulation share signal which can be used as both radar signal and interference signal is researched, optimization design theory is presented to achieve the efficiency of share signal.This dissertation concentrated on the research works listed below and achieved some creative results:(1) The necessary, feasibility and superiority of radar and jammer integration system research is systematic explained, the radar and jammer hardware equipment differences are detailed analyzed. Design principles and ideas of Radar and jammer integrated share signal are proposed.(2) Chaos theory is added to radar and jammer integrated share signal design, chaotic binary phase coded signal is presented as share signal with several shortcomings, to the question a new optimization principle is presented to achieve share signal optimization design, chaotic sequence is searched by objective function. Simulation experiments show that the new method is feasible and effective to improve detection efficiency and interference efficiency of share signal.(3) A new chaotic genetic hybrid algorithm is presented. Chaos characteristic is added into adaptive genetic algorithm circle, to avoid searching being trapped in local minimum and converge to a global minimum. Experiments results show that this algorithm can get globally optimal solution quickly and solve the problem of radar and jammer share signal optimization effectively.(4) Noise--phase coded modulation signal waveform is presented as a new style of radar and jammer share signal. Jamming efficiency of Gaussian white and low correlation sidelobe of Binary phase coded signal are combined. Binary phase coded signal is modulated based on Gaussian while noise. Experiments result show that this hybrid Noise-binary phase coded signal(NBPC)can be used as share signal.
