Summary:The authors describe a 94 GHz bistatic FMCW (frequency-modulation continuous-wave) radar under development for an aircraft landing system. Using a narrow vertical fan beam antenna, the system scans the runaway rapidly in azimuth, processes the radar returns, and obtains a realistic real-time runway image with sufficient information and resolution to enable a pilot to operate in and out of the airport in conditions with visibility as low as zero, without dependence on today's auto-land systems. This system may use an airport's glide slope indicator to approach the landing area. The range performance requirements of the landing system are illustrated.< >
