Electromagnetic environment automated testing device for aviational radio navigation station and method thereof

The invention discloses an electromagnetic environment automated testing device for an aviational radio navigation station and an electromagnetic environment automated testing method for the aviational radio navigation station. An antenna group consists of a plurality of antennas from the first to the Nth antennas which are respectively connected with input ports from the first to the Nth input ports of an antenna switch. The input ports from the first to the Nth input ports of the antenna switch are connected with the antenna switch respectively. The antenna switch, an antenna switch output port, a filter input port, a filter, a filter output port, a signal input port of a spectrum analyzer, a spectrum analyzer, a GPIB (General Purpose Interface Bus) data communication port of the spectrum analyzer, a GPIB data communication port of a computer and a computer are connected in sequence. According to the electromagnetic environment automated testing device for the aviational radio navigation station and the electromagnetic environment automated testing method for the aviational radio navigation station provided by the invention, the uncertainty and difference of test results among different test units in the test process are reduced, the accuracy and uniformity of measurement are ensured, thereby realizing the automated measurement, reducing the labor intensity, and improving the measuring efficiency tremendously.
