The invention discloses a novel design method for a high-cost-performance-ratio low-scattering support. The novel design method includes the following steps that S1, according to the bearing requirement, the diameter of a cylinder contained in a shape support is determined; S2, according to the diameter of the cylinder, an outline shape line of the external support is selected; S3, the outline shape line and lengths of all sections of the shape support are simultaneously optimized; S4, the electromagnetic scattering characteristic of the support is calculated, if the requirement is met, calculation is completed, if calculation is completed, the requirement is not met, the method returns the step S3, and optimizing is continuously carried out. The novel design method has the advantages that the support shape is optimized and designed, the strength of the support and the electromagnetic characteristic are separated, the shape support has the low scattering characteristic, the cylinder is arranged inside the shape support to be responsible for bearing, and the aim of increasing the cost-benefit ratio is achieved.
Description
technical field [0001] The invention relates to the technical field of radar target characteristic testing, and specifically designs a method for designing a low-scattering bracket and a corresponding bracket. Background technique [0002] During the measurement of electromagnetic scattering characteristics, it is necessary to support the measured target to a certain height, so that the measured target can rotate or pitch in the air, so as to imitate the various states of the measured target in actual work, and pass in the corresponding orientation Set test points on the ground to obtain the electromagnetic scattering characteristics of the measured target. [0003] The brackets and support technologies that have been used include rope suspension, polystyrene foam brackets, and dielectric rod brackets. However, with the development of target characteristics, target recognition, and stealth technology, it is necessary to perform amplitude and phase measurement, low RCS measu...
