The invention relates to an icing detection device and a detection method. The device comprises at least two ultrasonic transduction parts which are used for transmitting ultrasonic signals to a target object and receiving echo signals of the ultrasonic signals; the center frequencies of ultrasonic signals emitted by the ultrasonic transduction pieces are different; the delay part is arranged on the side, close to the target object, of the ultrasonic transduction part, is connected with the ultrasonic transduction part and is used for delaying the time when the ultrasonic signal reaches the target object. The thickness of a thin ice layer can be calculated by selecting the echo signal data corresponding to the ultrasonic transduction piece with the high frequency, and the thickness of a thick ice layer can be calculated by selecting the echo signal data corresponding to the ultrasonic transduction piece with the low frequency. And the icing thickness detection range is expanded.
