ATRD series, 76-81GHz FM FMCW radar products (also known as millimeter-wave radar) have important applications in remote target detection, long-range imaging and multi-spectral imaging in strong smoke and dust environment, and can detect smaller targets and achieve more accurate positioning than microwave radar, with higher resolution and stronger confidentiality.

What is millimeter wave electromagnetic wave. Usually, the electromagnetic wave in the frequency domain of 30-300GHz (wavelength is 1-10 mm) is called millimeter wave, which is located in the overlapping wavelength range of microwave and far infrared wave, so it has the characteristics of both spectra. The 76-81GHz band of this product is the least understood and applied by human beings so far, and it has the following characteristics:

Excellent transient performance

Wide bandwidth

Coherence

Low power consumption

Strong penetrability

Easy to be absorbed by polar molecules

As a 78GHz band radar used in industrial measurement, the high-precision and non-contact level and liquid level measurement has incomparable advantages compared with other ordinary microwave pulse radars and guided wave radars, and its extremely narrow beam and penetration ability can better adapt to ultra-complex working conditions without weakening the measurement performance.

 

 

Features

The electromagnetic wave emission angle of the product is less than 3 degree, which is suitable for measurement in narrow space or guided wave pipeline

The product can reach the measuring range of 120m, which is suitable for the measurement of super-large storage tanks

The blind area of product measurement is 7-8cm, which is suitable for the measurement of small storage tanks

The product has extremely high measurement accuracy and is suitable for high-precision measurement

The product has rich echo processing algorithms and empirical data of various working conditions; It has unique advantages over other similar products in extremely harsh working conditions such as strong dust and steam, or in the application of storage tanks with special processes such as stirring and heating rods
