Multichannel radar system for motor vehicles

摘要: A multichannel radar system for use on a motor vehicle has plurality of transmission and reception channels each composed an AM or FM signal generator generating including carrier which is amplitude- frequency-modulated by modulation signal, antennas radiating the generated receiving return reflected obstacle, amplifier amplifying received either detector detecting amplified mixer mixing with thereby to generate beat signal. power supply circuit supplies DC voltages respectively generators amplifiers respective in time-division multiplex manner at successive times. processor calculates distance up obstacle based phase difference between detected signals frequencies channels.
