| Abstract: |
| Radio beacon is necessary equipment for dynamic self-test of vessel carrier's radio measuring and controlling equipment. A beacon design method based on quadrature frequency-conversion technology was put forward. The parameters of the beacon were set flexibly through MCU control. Sidebands and local oscillator's leakage were suppressed in circuit implementation.Real application showed that the beacon works reliably and its performance meets requirements. The purpose was to provide technical supports for naval adjustment of vessel carrier's radio measuring and controlling equipments. |
