INDEPENDENT AIRCRAFT LANDING MONITOR SYSTEM

摘要

An aircraft landing monitor which is independent of ground-based guidance systems and which includes an antenna comprising an elongated housing pivotally mounted about a vertical axis for horizontal movement in the forward portion of an aircraft. The housing supports an edge-slotted waveguide array which is mounted in an elongated horn reflector to thereby direct an antenna radiation pattern forward of the aircraft which is narrower in the azimuth than in the elevation plane. A motor oscillates the antenna housing about the vertical axis to sweep over an azimuth angle sufficient for airport runway detection during a glideslope approach to the runway by the aircraft. Radar transmitter and receiver circuits transmit and receive pulse radar signals via the antenna for radar detection of the runway. A radarscope mounted in the cockpit control panel is responsive to the radar transmitter and receiver for visually displaying an approaching airport runway in real-world linear perspective.
