Vehicle-mounted radar system and detection method

摘要: Modulation frequency setting device sets the modulation on basis of vehicle speed data from a detector and detected range data, causing low oscillator to generate signal set frequency. A transmitter transmits an electromagnetic wave (e.g., infrared light) which have been modulated with signal. phase comparator detects difference between output, operating produces data. Relative unit finds relative based In case high speed, is extend detection range. If object in short distance detected, limit range, thereby enhancing resolution.
