Abstract
In a radar device, a hypothesis selector selects one of first to third hypotheses based on velocity-accuracy posterior distributions after a preset number of distribution calculations. The first hypothesis assumes that an observed velocity of an object is an aliased relative velocity when the relative velocity is higher than an upper limit of an observable velocity range. The second hypothesis assumes that the observed velocity is an unaliased relative velocity. The third hypothesis assumes that the observed velocity is an aliased relative velocity in a case where the relative velocity is below a lower limit of the observable velocity range. The velocity-accuracy posterior distributions are respectively calculated for the first to third hypotheses from velocity-accuracy prior distributions and a detection result of observed velocities for the preset number of distribution calculations.
