Description

Technical Field

[0001] The present invention relates to the technical field of potential measurement, and particularly relates to a potential measurement device and method for a new type of holographic radio. Background Art

[0002] Potential measurement is a core technology for detecting the distribution of electric potential energy on the surface of an object or in space, and is widely used in fields such as the safety monitoring of power equipment, the design of electronic components, the analysis of bioelectrical signals, and the research of materials science. Traditional methods mainly rely on contact probes or capacitive sensors to obtain local potential values through direct contact or near-field coupling, but are easily limited by measurement interference, low spatial resolution, etc., and it is difficult to achieve global dynamic monitoring in complex scenarios. With the progress of radio technology and computational imaging, non-contact potential measurement has become a research hotspot.

[0003] Traditional potential measurement technologies rely on contact probes and have problems such as high operation risks and low resolution. Although non-contact measurement methods avoid physical contact, the signal acquisition and processing structures of existing devices are difficult to achieve high-resolution potential imaging. For example, devices based on electric field coupling usually use single-point or sparse array sensors and cannot obtain complete spatial phase information. Therefore, a potential measurement device and method for a new type of holographic radio are proposed. Summary of the Invention

[0004] To this end, the present invention provides a potential measurement device and method for a new type of holographic radio to solve the above problems in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

The array includes multiple omnidirectional microstrip patch antenna elements, which are evenly distributed on the hemispherical surface. Each antenna element is equipped with a low-noise amplifier, and the noise figure is lower than 2 dB.

[0011] Furthermore, the multi-channel signal receiving and preprocessing module uses a 256-channel parallel acquisition card. Each channel is equipped with a 14-bit analog-to-digital converter, with a sampling rate of 20 GS / s, supporting the acquisition of real-time phase and amplitude information. It has a built-in digital down-converter to convert high-frequency signals into baseband signals, reducing the amount of data processing. An integrated phase calibration circuit is used to eliminate the phase deviation between channels through a reference signal, ensuring signal consistency. The signals of each channel of the signal transmission and synchronization unit are transmitted to the holographic processing and electric potential calculation system through high-speed optical fibers.

[0012] Furthermore, the signal preprocessing module realizes real-time filtering based on a field-programmable gate array, uses a finite impulse response filter to eliminate noise and interference, and performs phase unwrapping processing on the signal to correct the phase distortion caused by the geometric layout of the antenna array.
