A multi-probe array microwave imaging system and switch control method

Abstract

Aiming at the disadvantages of slow measurement speed and low test efficiency due to various delay times such as operating system delay, bus communication delay, and software interrupt delay in the conventional switch control software coding implementation method, the present invention proposes a system using A multi-probe array microwave imaging system and a switch control method for a host triggering a pulse signal, including: a main control computer, a microwave signal transceiver and data acquisition device, a switch array, a multi-probe antenna transceiver array, and a switch control module. In addition to the start command, the entire control The process is realized by the trigger pulse of the hardware, without software intervention, which greatly improves the real-time performance and stability; the use of the hardware pulse signal effectively avoids the operating system delay, bus communication delay, and software interrupt delay in the software coding control process. Various delay times, such as time, realize the minimum delay control in the whole control process.

Description

technical field [0001] The invention relates to the field of microwaves, in particular to a multi-probe array microwave imaging system, and also to a switch control method for the multi-probe array microwave imaging system. Background technique [0002] The multi-probe antenna array microwave imaging system does not require the relative movement between the measured target and the test equipment. It has the advantages of fast test speed, convenient operation, and simple equipment composition.
