3.4

Image Processing

Image processing is processing that is performed on data input through scanning and enables

easy deciphering of objects that are being probed for from the scanning results.

This radar contains the following five types of image processing:

a)
b)
c)
d)

Manual surface wave processing
Peak

processing

Reproduction of original image
Fixed surface wave processing
Deduction processing

3.4.1

Manual surface wave processing

Manual surface wave processing is used when the effect of reflection near the surface of the

concrete on the scanning results can not be completely removed. (See Figure 3-12.)

(1) Move the cursor to a location where there is not an object that is being

probed

A: Before processing

B: After processing
