Glossary of Terms

A mode

Displays received waveform as it is. The conditions of concrete directly
underneath the Handy Search are displayed as reflected waveform in real
time.

B mode

Displays the vertical cross section of a scan point by gradating the
reflected waveform shown in A mode according to reflection intensity and
continuously displaying it.

BA mode Displays both B-mode and A-mode images at the same time.

Real time
Auto surface wave

processing

Image processing that uses internal fixed surface wave data to
automatically remove the wave reflected from the surface of the concrete
during scanning and only shows the reflected wave from rebar etc.

Real time

Manual

Deduction

processing

Image processing used in the case that the effect of the reflected waves
from the surface of the concrete can not be fully removed using the
internal fixed surface wave data of the real time auto surface wave
processing. Thus, reflected waves in the form of stripes remain in the
scanning results.
Image processing where an arbitrary line is designated while scanning.
The data of the designated line is subtracted from the scanning results
data, and the reflected wave from the concrete surface is automatically
removed. Thus, only the reflected waves from rebar etc. are shown.

Manual

Surface wave
processing

Image processing where an arbitrary line is designated from scanning
results. The surface portion of the data from the designated line is
subtracted from the scanning results data, and the reflected wave from
the concrete surface is automatically removed. Thus, only the reflected
waves from rebar etc. are shown.

Peak processing

Image processing that shows only the waveform of the first peak on the
+side of the scanning results.
This enables removal of multiple reflected signals and only displays the
upper rebar.

Fixed surface

wave processing

Image processing that uses internal fixed surface wave data to remove
the wave reflected from the surface of the concrete and only shows the
reflected wave from rebar etc.

Deduction

processing

Image processing where an arbitrary line from the scanning results is
designated and the designated line is subtracted from the scanning
results data. Stripe reflected waves throughout the entire depth, such as
reflected waves from the concrete surface and reflected waves from the
rear surface etc., are removed and only the reflected waves from rebar
etc. are shown.

Reproduction of

original image

This processing restores the image processing result to the original state
and displays unprocessed raw data.

Distance feed

system

Method that performs scanning in accordance with Handy Search's
traveling distance, using the distance detector mounted on the wheels of
the Handy Search.

Time feed system

Method that performs B-mode scanning at preset time intervals,
regardless of movement of the Handy Search.

Relative dielectric

constant

Object-specific coefficient. The radio wave propagation rate changes with
the value of the relative permittivity. Therefore, the wave propagation
velocity and scanning depth change change based on the relative
permittivity of the concrete. Calculation error of scanning depth can be
reduced by setting a depth calibration value.

1 Description of Equipment

This equipment is indispensable for repairing/rebuilding and maintaining reinforced

concrete structures using its accurate and speedy diagnostic technology.

The Handy Search concrete internal probe vehicle, NJJ-95B, (hereafter called this

radar) radiates electromagnetic waves through the surface of concrete and receives

reflected signals from objects found inside such as reinforcing steel bars, cavities, or

other objects that have different electrical characteristics from concrete. Object
position and depth are then displayed and recorded as image data.

CAUTION

Making a judgement on the search results considering the depth sensing
capability of the NJJ-95B:
Since the depth sensing capability of the radar is subject to the conditions of
the object of investigation, judging the search results with no consideration of
the depth sensing capability may cause the accidental cutting of rebar.

1.2 Features

This device has the following features:

(1) The material of the object to be scanned can be either metallic or non-metallic

Reflected electromagnetic waves are generated at an interface when the

electrical property of an object is different from that of concrete. Thus, this radar

can probe polyvinyl-chloride pipes and cavities (dependent on the position and

size) as well as the reinforcing steel bars. Note that polyvinyl-chloride pipes and
cavities echo weakly in compared with the reinforcing steel bars.

If a polyvinyl-chloride pipe or cavity is near or below the reinforcing steel bars,

the reflected signals from the polyvinyl-chloride pipe or cavity may not be

obtained due to the strong reflected signals from the reinforcing steel bars. Thus,
care should be taken when you make a judgment on the search results.

(2) Detects rebars that cross the scanning direction

Rebar that cross the scanning direction transmit a large magnetic wave

reflection. On the other hand, rebar that is parallel to the scanning direction

transmit a smaller magnetic wave reflection. Even if scanning is performed

above rebar that is parallel to the scanning direction, this device can still detect

any rebar that is crosswise to the scanning direction.

(3) Obtaining continuous scanning results

The scanning results are obtained as a representation of the vertical cross

section of the inside of concrete. Thus, a comprehensive view of the internal
concrete conditions can be obtained.

(4) Obtaining scanning results at the site

Handy Search does not need to be secured to the surface of concrete.

Scanning is carried out while Handy Search is moved and results concerning
the internal conditions of the concrete can be provided immediately.

(5) Saving and reading scan data

Using a compact flash memory, scan data can be saved and reopened

(maximum of roughly 50 sets of data can be saved in text format for a depth of

15 m using a 512 MB compact flash). The data can also be loaded from the
compact flash memory card into a PC by using a card reader or the like.

(6) Printing without cable connection

The unit is equipped with IrDA, therefore, printing can be performed without

using a cable using a DPU-3345 series printer.

‑3‑

However, the IrDA optical receptors for this unit and the printer must be set

facing each other at a distance of 50 ~ 500 mm (without any obstacles between
them).

(7) Performing real time automatic surface wave processing

Internal fixed surface wave data is used to automatically remove the wave

reflected from the surface of the concrete during scanning enabling the showing
of the reflected wave from rebar.

Furthermore, surface wave processing can be switched to processing that

uses scan data surface waves during scanning (real time manual deduction)
enabling highly accurate surface processing.

(8) Displaying the data of an arbitrary point after scanning (scroll function)

This radar can store 15m woth of data at a time and display the data of

arbitrary points continuously.

(9) Changing sensitivity and performing image processing for scan data

This radar can display scan results after changing sensitivity or performing

image processing (manual surface wave processing, peak processing,

reproduction of original image, fixed surface wave processing, or deduction

processing). Thus, performing a scan test again with a new sensitivity setting is
not necessary.

(10) A mark can be displayed in the scan results using the cursor mark function.

A maximum of 7 cursor marks can be placed in the scan results to display the

scan position and depth of the mark.

(11) Providing the screen inversion function

(11) Screen inversion function is available

In case of scanning from right to left on a wall surface, the display on the

screen is upright (normal). In the case of scanning left to right, the display will

be inverted.

Therefore, the user can achieve the correct display by performing the scan

either right to left or left to right.

(12) Recording of date and settings

The main unit records the date and settings (data number, sensitivity, etc.)

using a backup function. When data is output, the date and settings are
recorded.

‑4‑

(13) Compact and light weight

This radar weighs only about 1.1 kg, so it is easy to operate.

(14) Operating with the battery pack and commercial power supply

This radar can operate with the battery pack for about 1.5 hours (at normal

temperature). It can also operate with the commercial power supply when an AC
adapter (optional) is used.
