Detailed Description
The invention is explained in further detail below with reference to the figures and the embodiments.
As shown in the figure, the high-speed towing inflatable floating body target comprises an inflatable floating ball 1, a flexible radar corner reflector 2 arranged inside the inflatable floating ball and a towing rope 3 arranged at the tail of the inflatable floating ball 1, wherein the inflatable floating ball 1 takes the floating ball as a main body, the surface of the inflatable floating ball is provided with a plurality of handles 12, rope buckles 13, rope buckles 14, a pocket-shaped trawl 15, an inflation valve 16 and a watertight zipper 17, and the inner wall of the inflatable floating body target is provided with a plurality of rope buckles 14 which are uniformly distributed; handle 12 evenly distributed is on the spheroid surface for the operation is retrieved in the input of body target or, the rope fastening 13 distributes along sphere longitude and latitude line cross for fixed pocket shape trawl form, inflation valve 16 is used for external gas charging equipment to aerify for the target body, watertight zip fastener 17 is used for opening back installation and adjustment flexible radar reflector, hang rope fastening 14 and be used for installing flexible radar reflector, pull flexible radar reflector and expand when the target body aerifys the shaping, pocket shape trawl 15 includes net rope 151 and D type knot 152, cross distribution on net rope 151 is along the sphere longitude and latitude line, D type knot 152 sets up at the net rope afterbody, makes things convenient for the installation of haulage rope, and cross network structure has increased the lifting surface area of floater when being dragged, can the splendid protection spheroid, avoids the target body to take place to warp when dragging and breaks.
The flexible radar corner reflector 2 is composed of a plurality of flexible corner reflectors, and when the inflatable floating ball is inflated and formed, the flexible radar corner reflector is automatically unfolded and formed to form a radar spherical omnidirectional isotropic reflection structure. The target body can be effectively prevented from rolling to change radar reflection signals when being dragged at a high speed or impacted by sea waves.
In this embodiment, a weight-bearing sinker 4 with a tow rope is included to stabilize the target. The PVC net clamping cloth for the floating ball is welded by a high-frequency hot melting technology. The material is light and convenient, has good tolerance and can be repeatedly folded, thereby providing a basis for integral folding for the floating body target.
