高频地波雷达系统优化控制的研究与建模

摘要

现代电子工业技术的发展使高频地波雷达的功能不断扩增，导致雷达系统控制十分复杂。因此，需要通过系统的性能评估、优化及智能控制使之能够在各种情况下发挥其最大效能。依据高频地波雷达的特点和探测目标类型进行系统建模仿真。考虑不同模糊控制方法在高频地波雷达系统中的可行性，将遗传算法和粒子群优化算法等方法与模糊控制结合实现对雷达系统的优化控制。通过对雷达信号频率、功率和相参积累时间的模糊控制达到期望的工作性能。利用 Matlab设计 GUI控制界面。%The development of modern electronic industry makes the radar functions increase rapidly, which leads to the radar control system more complicated.Therefore,performance evaluation,optimization, and intelligent control of complex electronic systems are needed to develop the maximal efficacy of radar.The paper processes system modelling and simulation based on the style of target and characteristic of high fre-quency surface wave radar(HFSWR).Considered the feasibility of different fuzzy control methods in the HF-SWR system,the paper combines the genetic algorithm and particle swarm optimization with fuzzy control to achieve optimal control of radar system.We make radar reach expected performance by controlling radar working frequency,power and coherent integration time.The GUI control interface is designed by use of Matlab.
