The invention relates to an intelligent flying robot capable of perching on walls at different inclination angles, and belongs to robots and aircrafts.The intelligent flying robot comprises a flying system, an adsorbing system and a control system, the flying system is a robot body, the adsorbing system is installed on the flying system, the control system controls the flying system and the adsorbing system so that the flying robot can be adsorbed on the walls at different inclination angles, and the flying state and the adsorbing state can be switched freely.The intelligent flying robot has the advantages of having the function of perching on the walls, and as perching power is far lower than flying power of the robot, the time for detecting a fixed target is substantially prolonged.Intelligent adsorption of the robot is achieved by adopting a wall inclination angle measurer, and the flying state and the adsorbing state can be switched freely.The flying robot can be adsorbed on the walls at different inclination angles, and the application range of the robot is broadened.The robot is tightly attached to the walls during adsorption, and therefore concealing performance is greatly improved.An antiskid plate and supporting legs are adopted to assist in adsorption, the adsorption effect is stable, and the robot is prevented from slipping during adsorption.

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.
