Safe stopping distance detector, antenna and method

摘要: An FM/CW radar system is disclosed for determining a safe stopping distance between moving vehicle and potential obstacle. The signal modulated linearly over several slopes. A microstrip phased array transmit/receive antenna also having hybrid tap, corporate feed structure. Signals from the are amplified filtered, passed through an analog to digital converter processor, which performs Fast Fourier Transform on signals convert them time domain data frequency data. then used solve target range doppler equations, determine distances, sound or display alarms if has been violated. sensitivity control adjusts road conditions operator reaction variations.
