SYSTEM AND METHOD FOR MEASUREMENT OF MATERIAL PROPERTY USING VARIABLE REFLECTOR
ABSTRACT A system and method for measuring a material includes at least one transmitter for transmitting a first signal and a second signal. A variable reflector reflects a portion of the first signal at a first reflecting property to produce a first reflected signal, the portion of the first signal having traveled through the material. The variable reflector also reflects a portion of the second signal at a second reflecting property to produce a second reflected signal, the portion of the second signal having traveled through the material. A receiver receives the first received signal and the second received signal, the first received signal includes the first reflected signal having traveled through the material and the second received signal includes the second reflected signal having traveled through the material. The first reflected signal and the second reflected signal providing an indication of at least one property of the material. The at least one property includes permittivity, attenuation, anisotropy, and frequency dependency of the material. Date Recue/Date Received 2020-10-22

Data acquisition for a ground penetrating radar system
A system and method for measuring ground penetrating radar data is described which includes controlling the timing for generating stimulus electromagnetic waves and the sampling rate of reflected electromagnetic waves in response to the stimulus electromagnetic waves. Generally, the timing is adjusted for spatially over-sampling the ground penetrating radar data. The speed of the system can also be adjusted based on the measured data.

An apparatus for transporting a sensor having a sensing surface at an operational distance from a target surface is disclosed. The apparatus includes an upper frame and spaced apart parallel front and rear struts. The upper ends of the struts are connected to the upper frame. The lower ends of the struts are connected to the sensor. The front and rear struts pivot about the upper frame to move the sensor in response to an obstacle on the target surface, The sensor pivots about the lower ends of the front and rear struts to maintain the sensing surface in substantially parallel orientation to the target surface. The angle between the sensing surface and the front and rear struts is less than 90°.
An apparatus for transporting a sensor may comprise a sensor having a sensing surface at an operational distance from a target surface. The apparatus may include a frame and front and rear struts pivotally connected to the frame. A deflector may be connected to on of the front and rear struts, and the sensor. The deflector may be located forward of the sensor and upon a deflection surface impacting an obstacle on the target surface, the deflector can be adapted to pivot the front and rear struts upwardly.
