Electromagnetic Scattering Theory of Car Body Imaging Using Scanning Millimeter Wave Radar
Technical subjects of automatic driving system and safety transport system are very important problems. Automatic driving and cruising systems using microwave and millimeter radars in the cars are sensor systems for measurements of distances among driving cars, and recognition of road environments. Millimeter wave radar of short wavelengths using short pulses of millimeter wave carriers yields precise distance measurement for distance control system between driving automobiles, and auto-breaking system. Image information is given by reflected waves by scanning millimeter beam waves, like optical vision information. Comparing with optical waves, millimeter waves have less attenuation characteristics due to rains, mist, fog, and snows, and can give fairly good size resolution. Shape image recognition systems of car bodies with scattered and reflected waves in scanning millimeter radars, are very useful for ITS. Temporal and spatial characteristics of electromagnetic scattering and reflection by driving car bodies are studied by beam spectral function method. Fundamental characteristics and application of scanning millimeter wave radars of synthetic aperture type and multi-wavelengths for image recognition of car body are shown.
