  • Method for characterizing air traffic control radar beacon system antenna patterns
    Patent number: 5969664
    Abstract: A method for measuring and characterizing the Air Traffic Control Radar Beacon System without interrupting service which comprises a computer-controller system which captures the beacon radar system emissions during one radar rotation and software which extracts and plots the two antenna signal patterns. Data is collected for 50 microseconds during each degree of antenna rotation, triggered by the first pulse of the three pulse signals, and is then stored in separate omni-directional and directional arrays for subsequent plotting. Data is also collected for 50 microseconds during each one-tenth degree of antenna rotation within the directional antenna main lobe.
