摘要
针对传统甚高频全向信标(VOR)检测系统体积大、实时性差的问题,设计一种小型化的VOR实时检测系统。该系统使用AD9361对信号采集转换,主控部分使用Xilinx公司ZYNQ系列芯片,PL部分完成信号的预处理,PS部分计算信号参数指标,PL与PS通过DPRAM进行数据交换。整体方案通过软硬件联合开发,极大地提高系统检测效率。测试结果表明,该系统对VOR信号可以进行稳定、实时地检测分析,检测效率可达到0.5 s/次,测量精度较高并满足ICAO的规定,同时具有较高的应用价值。
Aimed at the problems of large volume and poor real-time performance of the traditional VHF Omnidirectional range(VOR)detection system,a miniaturized VOR real-time detection system is designed.AD9361 was used in the system for signal acquisition and conversion,Xilinx ZYNQ chip was used in the main control part,PL part completed signal preprocessing,PS part calculated signal parameters,and the PL and PS exchanged data through DPRAM.The overall scheme was jointly developed by software and hardware,which greatly improved the efficiency of system detection.The test results show that the system can detect and analyze VOR signal stably and in real time,the detection efficiency can reach 0.5 s once,the measurement accuracy is high,and it meets the ICAO regulations,and it has high application value.
