Description

A development and testing platform for the acquisition and control system of an all-round scanning radar antenna in a hole

Technical Field

The invention relates to the technical field of borehole radar, and in particular to a development and testing platform for an in-hole omnidirectional scanning radar antenna acquisition and control system.

Background technique

Borehole radar technology has excellent performance in detection depth and accuracy, and is therefore widely used in fields such as underground oil and gas resource exploration and advanced detection of coal mining.

The acquisition and control system is the core of borehole radar technology. It is used to achieve precise control of the direction of borehole radar directional detection and precise tracking of the direction during scanning detection. In the development process of the borehole all-round scanning radar antenna acquisition and control system, there are usually two ways to test the rotation scanning function. One is to place the core components of the radar such as the control unit, posture monitoring unit, radar radiation surface, etc. directly on the table for testing. This method is simple and fast, but because the core components of the radar are in a state of continuous rotation and scanning during actual work, this method often causes wire entanglement, which affects the test effect. Another way is to install the core components of the radar into the antenna casing for testing. Although this test method avoids wire entanglement, the disassembly and assembly process is cumbersome and it is difficult to meet the needs of repeated testing during the development process.

Therefore, it is necessary to design a development and testing platform to make the development and testing process of the borehole omnidirectional scanning radar antenna acquisition and control system simpler and more efficient.
