Abstract

The invention discloses a structure-adjustable radar speed measurement device which comprises three supporting rods and a supporting column. Three limit slots are formed in the side wall of the supporting column and equidistantly distributed along the circumferential direction of the supporting column, the direction of a long axis of each limit slot is parallel to the axial direction of the supporting column, the inner axial top end of each limit slot is rotatably connected with one supporting rod with a telescopic rod structure, the limit slots are used for containing retracted supporting rods, and a radar box is mounted at the axial top end of the supporting column through a mounting plate. The structure-adjustable radar speed measurement device is easy to carry and handle.

Description

technical field [0001] The invention relates to a radar device, in particular to a radar speed measuring device with an adjustable structure. Background technique [0002] The speed radar mainly uses the Doppler Effect principle: when the target approaches the radar antenna, the frequency of the reflected signal will be higher than that of the transmitter; conversely, when the target moves away from the antenna, the frequency of the reflected signal will be lower than the frequency of the transmitted signal. probability. In this way, the relative speed between the target and the radar can be calculated by changing the value of the frequency. It has been widely used in police speed testing and other industries. The portable radar speedometers currently used are all supported by a tripod with a fixed structure, which is inconvenient to carry and carry. Contents of the invention [0003] The technical problem to be solved by the present invention is that the portable radar...
