An FMCW radar method is presented in which a radar system of a motor
vehicle emits and receives radar waves, and in which a distance between
an object and the motor vehicle is determined from a frequency shift
between transmitted and received radar waves, and in which a speed of an
object is determined from phase positions of received radar waves. The
method is defined by the fact that in first time periods (T_A, T_B) it is
carried out for objects in at least a first partial area (A, B) of the
surroundings of the motor vehicle, and in second time period (T_C, T_D,
T_E, T_F, T_G) distances, but not speeds, are determined for objects in
at least a second partial area (C, D, E, F, G) of the surroundings.
