This disclosure provides an antenna testing system and method, relating to the field of antenna technology. The testing system includes a voltage loading device, the output of which is connected to the input of a phased array antenna; a field testing system for testing the antenna parameters of the phased array antenna; and a computer device, the output of which is connected to the voltage loading device, and the input of which is connected to the field testing system. In real-time mode, this disclosure allows for the pre-testing of the target loading voltage corresponding to the phased array antenna when its performance most closely approximates the reference antenna parameters during beam radiation. Since the tested target loading voltage is obtained through actual testing using the field testing system, the accuracy of the tested target loading voltage is guaranteed, thus ensuring the antenna performance of the phased array antenna in subsequent use.

This invention provides a downhole in-situ rock scratching tool, relating to the field of petroleum engineering technology. It includes a tool housing, a scratching module, a control module, and a data acquisition module. The tool housing includes an axial channel; the scratching module is disposed within this axial channel and includes an adjustable cutter head support and a cutter head. The cutter head support can drive the cutter head to extend or retract radially along the tool housing. When the cutter head is in the extended position, it can form scratches on the downhole rock in situ. The control module includes a drive mechanism and a linkage mechanism. The drive mechanism can drive the scratching module to switch between the extended and retracted positions via the linkage mechanism. The data acquisition module is used to collect and upload force data on the cutter head. This invention can form continuous scratches on the downhole wellbore. Combined with the data acquisition module, it can simultaneously collect scratch force data for the entire test section. A single downhole run can complete continuous testing of a relatively long well section, resulting in short operation time, fast data output, and significantly reduced direct and time costs for obtaining rock mechanical parameters.
