摘要： PROBLEM TO BE SOLVED: To precisely find an aperture of a buried pipe based on a reception signal level, using an underground survey radar.
SOLUTION: This pipe diameter estimation method stores a correspondence table of a pipe diameter in a reference depth to the reception signal level (S1), conducts usual survey (S2), and finds a buried depth and a dielectric constant of a soil, based on different propagation times from two lines of reception systems (S3). A reception signal is inverse-TC-processed (S4) to find the reception signal level for estimation. The correspondence table in a reference signal is corrected based on the depth and the dielectric constant (S5), and the corrected table is compared with the reception signal level to estimate the pipe diameter (S6).

摘要： PROBLEM TO BE SOLVED: To provide a buried object surveying apparatus that is compatible with a comparatively thick wall and is easily handleable, and surveys the position of a target point provided on the back side being a back plane of a wall or floor, from its near-side surface by using a radar wave. SOLUTION: The buried object surveying apparatus 1 includes a display 2, an operation switch 3, a handle 4 for holding the buried-object surveying apparatus 1, and wheels 5 having a built-in encoder for detecting the position of movement. Moreover, the buried-object surveying apparatus 1 is operated on the near side of the wall, and a V-shaped target 10 is arranged on the back side of the wall. The V-shaped target 10 is a tapelike metal plate which reflects radar waves, and is stuck to the wall so as to stretch right and left at an angle of θ/2 with respect to a perpendicular axis (direction of gravity) passing a target point (point C).
