Definition of trihedral in English:

trihedral

adjective trʌɪˈhiːdr(ə)ltraɪˈhidrəl

(of a solid figure or body) having three sides or faces (in addition to the base or ends); triangular in cross section.
（三维体）三面形的（指除底面外有三个面的）；横断面呈三角形的
Example sentencesExamples
- Recently. sea-scatter data was collected from 1.9-11.5 GHz with trihedral reflectors.
- These results clearly demonstrate that the trihedral twist reflector of the invention produces an acceptable and usable cross polarized echo over a wide range of angles and frequencies.
- The other uses the trihedral corner reflector and the natural distributed targets.
- This German-made touring kayak uses a trihedral hull design to gain a unique balance of glide speed, carving agility, carrying capacity, stability, and comfort.
- Different trihedral angle configurations were generated using synthetic data for testing the authors’ approach of finding object orientation by angle to angle constraint.
- It is fascinating to look at the dihedral angles in trihedral acrons and compare those acrons which have been resolved with those that have not.
- Iceberg targets are known to have a combined surface and volume scattering mechanism while ships tend to have a combination of dihedral and trihedral surface scattering.

noun trʌɪˈhiːdr(ə)ltraɪˈhidrəl

A trihedral figure.
三面形
Example sentencesExamples
- The right-left ambiguity ratio, measured using 5-m trihedrals on both sides of the flight track, is about 10 dB for a single antenna element on receive.
- Similar substitutions convert the first law of cosines for trihedrals into the law of cosines for the sides of spherical triangles.
- Radar corner reflectors are simple trihedrals of aluminium that strongly reflect the radar signal back to the satellite.
- The mechanical mounting of the pod underneath the carrier aircraft ensures parallelism of the corresponding trihedrals with limited precision.
- One of the most interesting novelties of the volume was the so-called ‘moving trihedrals’ for twisted curves as well as surfaces so freely used in writings of Darboux and others.
- Reference targets that are supported include spheres, flat plates, square dihedrals and trihedrals, and circular cylinders.

Origin

Late 18th century: from Greek tri- 'three' + hedra 'base' + -al.
