1. A vehicular radar system for determining the deviation of at least one target about an automotive vehicle relative to a reference azimuth, comprising the combination of:

  • (a) means for transmitting a transmission signal;

    (b) means for sensing the transmission signal reflected from at least one target and received at two different locations as two different receive signals;

    (c) means for converting each of the two different received signals to two different doppler signals by homodyning each received signal with the transmitted frequency;

    (d) means responsive to the two different doppler signals for determining the sum of and the difference between the two different doppler signals; and

    (e) means for comparing the sum and difference to determine the deviation of the target from the reference azimuth.
