DESIGN AND IMPLEMENTATION OF VOR REAL-TIME DETECTION SYSTEM BASED ON ZYNQ

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.
