Abstract

In radar systems in which successive signals are compared to characterize the radar intelligence detected, variable phase shifts (or path length elongation), encountered in a flexible waveguide resulting from mechanical vibration, can be the source of serious error.

Phase Shift in Flexible Waveguide

In radar systems in which successive signals are compared to characterize the radar intelligence detected, variable phase shifts (or path length elongation), encountered in a flexible waveguide resulting from mechanical vibration, can be the source of serious error.

This is a method of reinforcing a flexible waveguide by utilizing a plurality of reinforcing strips 1 and 2 on the outside surface. Reinforcing strips 1 and 2 are arranged in pairs. Each strip of the pair is on diametrically opposite surfaces of the waveguide. Each succeeding pair is placed on the guide surface displaced by 90 degrees from the location of the preceding pair.

The strips are made of material such as beryllium and attached to the waveguide by welding. Thus, the capability of vibration to change the effective path length of the electromagnetic energy passing through the waveguide is minimized.
