摘要
为了提高比幅测向设备的测向精度,提出了一种改进的比幅测向系统,分析了六天线比幅测向系统的基本工作原理,研究并通过仿真实验证明了飞机在横滚或俯仰两种状态下会带来较大的测向误差。结果表明,改进的比幅测向系统能够消除测向误差,提高测向精度。
In order to improve the direction-finding precision of amplitude-comparison direction-finding equipment,this paper puts forward a kind of improved amplitude-comparison direction-finding system,analyzes the basic operation principle of 6-antenna amplitude-comparison direction-finding system,researches and proves that the airplane flying stance in the state of rolling or pitching may bring larger direction-finding error through the simulation experiment. The results shows that the improved amplitude-comparison direction-finding system can eliminate the direction-finding error and improve the direction-finding precision.
