ABSTRACT:
Automotive vehicle including a radar transceiver each including a heterodyne active IMPATT multiplier module arranged to receive a signal from a VCO, a first balance mixer arranged to receive a signal from a VCO, a second balance mixer arranged to receive a signal from a receive antenna and the IMPATT multiplier module and derive a first intermediate frequency signal, a first amplifier for amplifying the output of the second balance mixer and providing the amplifier output to the first balance mixer, and a second amplifier for amplifying the output of the first balance mixer. The vehicle also includes a processor which receives output from the second amplifier of each transceiver and generates a control signal for controlling one or more vehicular components based on the output from the second amplifier(s). The components can be part of a collision avoidance system, blind spot monitoring system and the like.
