A TPRF method for avoiding velocity measurement obscureness of a Doppler weather radar belongs to the field of weather radars, and aims at solving the problem of velocity measurement obscureness of the Doppler radar. The TPRF method is a special case of multiple-pulse repetition frequency detection technology and is also the development of dipulse repetition frequency (DPRF) detection technology.In TPRF technology, three pulse repetition frequencies forming two DPRF detections are used for detection, and two results detected by the DPRF are analyzed by the DPRF again, thereby expanding a velocity measurement range for twice. The velocity measurement range expanded by the DPRF can not realize the detection without obscureness in weather with strong convection. Under the condition that thedistance of the detection without obscureness is the same, the velocity measurement range of the TPRF is wider than that of the DPRF by two times at least, thereby realizing the detection without obscureness on most weather with strong convection. The key for implementing the TPRF is to choose three suitable pulse repetition frequencies and to provide a method for confirming the three pulse repetition frequencies of the TPRF so as to ensure the effectiveness of the TPRF method.
