Paper Abstract

A millimeter-wave radar designed for landing helicopters in brown-out conditions is described and data is presented from an initial flight test. The radar operates in a frequency modulated continuous wave architecture, determining range to target by calculating the difference between transmitted and returned frequencies. The millimeter-wave frequency band provides sand and dust penetration and allows for small apertures appropriate for helicopter mounting. This radar also uses a flat panel phased-array receive antenna and phase processor to sample multiple antenna beams simultaneously, an architecture that has previously been successfully used in passive millimeter-wave imaging systems. The radar presents a wide field-of-view image to the operator at a 3 Hz frame rate where range to the ground and obstacles is depicted in grayscale. The flight test showed the radar to be capable of depicting terrain height variations and obstacles such as buildings, vehicles, building materials, and even power lines. Reductions in noise and symbology improvements are necessary developments for a viable landing system.
