摘要
介绍了时差基线测向的原理,分析了测向过程中存在的模糊性问题和双基线系统余数定理解模糊的方法.根据虚拟阵元概念,解释了基线长度之比为互质数之比时多基线系统的相位解模糊算式,并提出了基于免疫算法的解模糊方法.阐述了基于免疫算法的机理,并建立免疫优化的实现方案.进一步提高了基线测向系统的鉴相能力,可实现多信号测向.仿真结果表明该方法是有效的.
Have introduced the base line of time difference to measure to principle, have analyzed to measure to the existent vagueness in course problem and two systematic remainder theorems of base line untie vague method. According to the fictitious first concept of battle array have explained the length of base line Zhi than is mutual prime number Zhi than the phase of the much system of base line untie vague calculate type, and have put forward based on immunity algorithm untie vague method. Have elaborated the mechanism based on immunity algorithm, and establishment the realization of immunity optimization scheme. Have raised base line further to measure to systematic lesson appearance ability, can realize signal to measure to. Emulation result shows that this method is effective.
