Comparison between Impulse and Holographic Subsurface Radar for NDT of Space Vehicle Structural Materials
A subsurface holographic radar using a multi-frequency signal has been developed for inspecting dieffectric construction materials. The characteristic feature of this device is the ability to obtain one-sided radar soundings/images with a high sensitivity and high resolution (2 cm) in the frequency band of 3.6-4.0 GHz. One promising application of the device is nondestructive evaluation of the heat protection system and other materials on the U.S. Space Shuttle, and proposed crewed exploration vehicle (CEV). The advantages of this continuouswave holographic radar over traditional impulse subsurface radars are discussed and illustrated by experimental results.
