Node voltage acquisition circuit and active stealth experiment device

Abstract

The invention provides a node voltage acquisition circuit and an active stealth experiment device, which relate to the technical field of DC active stealth experiments. The node voltage acquisition circuit comprises a processor, a decoder and multiple groups of analog electronic switches, wherein each analog electronic switch group comprises multiple analog electronic switches; the processor and the decoder are connected; each analog electronic switch in the same group is connected with the same port of the decoder; each port of each analog electronic switch is respectively connected with each node in a resistance network circuit; the processor is used for controlling each analog electronic switch group to be conducted sequentially through the decoder and controlling each analog electronic switch in the analog electronic switch group to be conducted sequentially to acquire the voltage value of the corresponding node. Through the above setting, the problems of inconvenient acquisition due to too many nodes in need of voltage acquisition in the resistance network circuit and long consumed time in the existing active stealth technology can be solved.

Description

technical field [0001] The invention relates to the technical field of DC active stealth experiments, in particular to a node voltage acquisition circuit and an active stealth experiment device. Background technique [0002] With the rapid development of passive stealth, the application range of stealth technology is becoming wider and wider, and it has received extensive attention. However, since passive stealth technology mainly relies on complex artificial metamaterials to achieve the purpose of stealth. Therefore, passive cloaking is limited by materials, and there are problems such as complicated manufacturing process and poor cloaking effect. [0003] In the prior art, for the above-mentioned problems of passive cloaking, a resistive network circuit can be used to achieve the purpose of active cloaking, and active cloaking also has the characteristics of flexible control methods and easy adaptability to various environments. In the process of realizing active invisib...
