An ultra wide band (UWB) device and a detect and avoid (DAA) method thereof are provided. The UWB device includes a detect and avoid (DAA) module block which detects a strength of radio signals received in a plurality of channels and determines communicability of the channels; a multitone generation block which generates a plurality of frequencies corresponding to the plurality of the channels and outputs one of the plurality of frequencies; and a controller which controls the multitone generation block to generate frequencies of an available channel which is determined to be communicable by the DAA module block. The method includes detecting a strength of radio signals received in a plurality of channels; determining communicability of the channels according to the detected strength of the radio signals; generating frequencies corresponding to a channel which is determined to be communicable; and transmitting or receiving a signal using the generated frequencies. |
