In the above embodiment:
since the late 19 th century is formally named, Terahertz wave bands are highly concerned by a plurality of countries in Europe and America, the Terahertz wave bands are the English translation of Terahertz unit, namely 100 GHz-10 THz electromagnetic radiation (also defined as 300 GHz-10 THz), the wavelength is in the range of 0.03 mm-3 mm, and the infrared and microwave technologies on two sides of the Terahertz wave bands are relatively mature on the electromagnetic spectrum.
The terahertz spectrum covers the rotational and resonant frequencies of organic macromolecules, including proteins.
The nondestructive testing is to utilize terahertz electromagnetic signals to have good penetrating power on most dry, non-metal and non-polar materials, and then combine various imaging technologies to carry out detailed detection on defects in fan blade materials and cables.
(3) The terahertz wave has low photon energy. Electromagnetic waves having a frequency of 1THz have a photon energy of only about 4meV, about one part per million of the X-ray photon energy, and thus do not produce harmful ionization of biological tissue, and are suitable for biopsy of biological tissue.
(4) One potentially significant application of terahertz technology is spatial wireless high-capacity, secure communications. With the development of space technology, the communication mode of the space technology will develop from the traditional air-ground single mode to the direction of air-ground and air-air combination. Compared with a microwave band, the terahertz communication has the advantages of wide bandwidth, good directionality, strong confidentiality, high safety and the like.
The laser radar is a radar system that detects a characteristic amount such as a position and a velocity of a target by emitting a laser beam. In terms of working principle, the radar antenna has no fundamental difference from microwave radar: the method comprises the steps of transmitting a detection signal (laser beam) to a target, comparing a received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, obtaining relevant information of the target, such as target distance, azimuth, height, speed, attitude, even shape and other parameters, thereby detecting, tracking and identifying the target such as an airplane, a missile and the like. The laser radar is composed of a laser transmitter, an optical receiver, a rotary table, an information processing system and the like, wherein the laser device converts electric pulses into optical pulses to be transmitted out, and the optical receiver restores the optical pulses reflected from a target into electric pulses to be transmitted to a display. The laser is used as a transmitting light source, and the photoelectric detection technical means is adopted. Laser radar is an advanced detection mode combining laser technology and modern photoelectric detection technology. The system consists of a transmitting system, a receiving system, information processing and the like.
The laser has very accurate ranging capability, the ranging accuracy can reach several centimeters, and the accuracy of the LIDAR system depends on the intrinsic factors such as the synchronization of the laser, the GPS and an Inertial Measurement Unit (IMU) besides the laser. With the development of commercial GPS and IMU, it has become possible and widely used to obtain high precision data from mobile platforms (e.g., on airplanes) via LIDAR.
Microwave radar sensing technology, as a special distance/displacement measurement means, can solve the measurement problem of short-range targets, and is also called short-range radar, and has been extended from military fields to civil fields, and is gradually applied in the aspects of level measurement, target identification, speed measurement, vibration monitoring, displacement monitoring, and the like. Compared with other sensing technologies, the radar sensing technology has the unique advantages of non-contact, rain mist dust resistance and the like, and gradually becomes an important sensing means in the field of short-range target displacement measurement.
The current structure displacement monitoring method cannot simultaneously meet the displacement measurement requirements of all-weather, high precision (millimeter level), long distance (hundreds of meters), low cost and the like of a building structure body, and is difficult to timely and effectively monitor the building state safety and early warn damage or accident occurrence. Therefore, research and development of a new displacement monitoring method are urgent and needed. Researches show that the microwave phase radar can work all weather by adopting microwaves as a propagation medium, and has huge potential, and the theoretical precision of the microwave phase radar can reach millimeter level or even submillimeter level. However, it has problems of transmitter leakage and multipath echo interference, which may reduce the radar measurement accuracy, limit the effective working distance, and even make the radar unable to work in severe cases.
Interferometric radar displacement measurement principle
The CW radar system transmits a single-frequency microwave signal to a target to be measured through a radar transmitting antenna, the target displacement is measured according to the phase difference between a target echo signal and a transmitting signal, and the phase difference between the transmitting signal transmitted by a radar host and the echo signal reflected by the target. The CW radar system is simple in ranging principle, transmits a single-frequency microwave signal to a target to be measured through a radar, and then calculates the displacement between the target and the target according to the phase difference between an echo signal transmitted back from the target and a transmitting signal. The transmitting signal and the echo signal are expressed by the frequency and the initial phase of the transmitting signal through a mathematical relation, and then the distance between a target and the radar is calculated through the time delay of the echo signal. In the calculation process, there is a small problem in the measurement of the phase, that is, the phase has periodicity, so that only the remainder part of the phase difference can be obtained when the phase difference is calculated, and the measurement of the target displacement is not influenced. When the target is displaced, the distance is changed, and the displacement of the target can be obtained through calculation. The calculation method has the limitation that the relative displacement can be intelligently calculated, and the absolute distance can not be measured by the method.
Target displacement measurement
Target displacement measurement is one of the main applications of interferometric radar today. Scientists begin to study the displacement measurement error of the interferometric radar in 2003 by experiments, in the experiments of the displacement measurement in a short distance, the displacement error of the interferometric radar is very small, and the main error is still because the output phase of the quadrature mixer is nonlinear, so the scientists continuously improve the displacement measurement by experiments, and finally replace the original analog mixer with the digital quadrature mixer, so that the error is controlled in the micrometer level, and the accuracy is greatly improved. Domestic scientists have made many studies on the problem that the range of the interferometric radar is limited, and have found that the effective measurement range of the interferometric radar can be enlarged and verified by changing the signal amplitude.
Practice proves that: the laser radar displacement measurement method and the microwave radar method are complementary, and the microwave radar method is suitable for measuring the displacement parallel to the observation direction; the laser displacement measurement method is suitable for measuring the displacement in the direction perpendicular to the observation direction.
In practice, the wind power foundation and the deformation and displacement of the tower barrel have the two characteristics, so that the laser microwave spectrum-superposed radar is a good choice.
Terahertz radar system
The terahertz spectrum contains abundant frequencies, has very wide bandwidth, can emit pulses of nanosecond to picosecond level at thousands of frequencies, and greatly exceeds the action range of the existing stealth technology. On the other hand, the wavelength of the terahertz wave is very short, approximately in the range of 30 um-3 mm, and is much shorter than the wavelengths of the microwave and millimeter wave, so that the terahertz wave can be used for detecting smaller targets and positioning more accurately. Therefore, the object can be made "invisible" regardless of whether the object is a shape-hiding object, a paint-hiding object, or a plasma-hiding object. The United states is the country which firstly puts forward the concept of the terahertz radar, and high-resolution radar experiments such as 0.2THz, 1.56THz, 0.6THz and the like are successively carried out, so that the feasibility of the terahertz radar is verified, and a foundation is laid for the development in the future. The terahertz radar is one of the development directions of future high-precision and anti-stealth radars.

The system has an international leading-level multi-thread processor architecture, can share a plurality of hardware resources, and saves the chip cost while providing the processing capacity of a considerable multi-core processor.
The module based on the domestic processor satellite navigation chip scheme is a BD/GPS dual-mode module with the minimum global volume, and has the characteristics of high positioning precision, quick starting time, low power consumption and the like.
Compare with simple big dipper chip producer, cell-phone chip producer has deeper understanding to the terminal location, include: a base station assisted satellite positioning technology, the fusion of various positioning schemes, the integration of a positioning chip and an application processor or a baseband processor, and the like. The Beidou mobile phone chip manufacturer actively supports the domestic mobile phone chip manufacturers to enter the Beidou chip research and development field, actively researches and develops a comprehensive positioning solution, and greatly improves the Beidou industrial chain.

Compared with the microwave band, the THz wireless communication has the advantages of wide bandwidth, good directionality and the like. With the development of aerospace technology, the range of human activities will gradually expand to the outer space, and a space high-speed communication system needs to be established. Compared with the frequency band used by the existing spatial communication, the spatial THz wireless communication has the following advantages: (i) in stratosphere and above (> 20 km), water vapor is very thin, the absorption of the water vapor to THz waves is greatly weakened, and as the Rayleigh scattering intensity is inversely proportional to the 4 th power of the wavelength and Mie scattering is weakened along with the increase of the wavelength, THz wireless communication in the near-earth space is expected to have better performance than short-wavelength wireless optical communication. (ii) As the atmosphere is a natural barrier of THz radiation, the THz space communication avoids the interference from earth radiation noise, improves the signal-to-noise ratio of THz signal detection, enables the ground not to monitor THz communication signals and improves the safety of THz wireless communication. (iii) The THz wireless communication technology is researched, blind spots of information sending, transmission and receiving in the THz frequency band are eliminated, and the THz wireless communication technology plays an important role in national security of China.
