摘要： A radar device including an ADC that performs slide sampling on frequency difference signals outputted from a mixer, and classifies sampling data about the frequency difference signals according to range bins based on a distance resolution corresponding to a pulse width set by a controller, and a speed discrimination unit that separates the sampling data about each range bin after being classified by the ADC according to relative speeds of objects. A distance and speed measurement unit calculates the distance to and the relative speed of an object which has reflected a transmission pulse by using the sampling data after being separated according to relative speeds by the speed discrimination unit.
