In order to enhance the design efficiency of vortex electromagnetic (EM) wave radar detection systems, a method for generating and controlling vortex EM waves based on amplitude-modulated concentric circular array (CCA) is proposed. This method allows for precise control of the vortex EM waves, ensuring accurate main lobe direction while effectively reducing sidelobes. Based on approximate orthogonal transformation, formulas for calculating the excitation amplitudes of each sub-circular array are derived and the time complexity of this method is negligible compared to search-based algorithms. Extensive simulation experiments are conducted and compared with the results obtained from the genetic algorithm (GA) approach, providing robust evidence of the effectiveness of this method(SLL © Published under licence by IOP Publishing Ltd.

Vortex electromagnetic (EM) waves can provide more target information, which is orbital angular momentum (OAM), than traditional plane waves in the field of radar detection. By emitting multiple different OAM modes of vortex EM waves to the same target, the azimuth information of the target can be obtained. The Linear Frequency Modulated (LFM) radar is often used in current OAM radar design. At present, researches on vortex EM wave imaging usually requires the emission of a large number of OAM modes to irradiate the target. Although many achievements have been made to significantly reduce this number, it is often accompanied by problems such as loss of azimuth imaging accuracy or poor real-time performance in practical applications. In response to this issue, this paper proposes a near-field target detection method based on modal baseline using vortex EM waves. By alternately emitting vortex EM waves with least OAM mode difference of 1, the method achieves range-velocity imaging while the OAM mode phase information is not blurred. The target detection task is carried out in the range-Doppler dimension, avoiding the problem of azimuth imaging. Through signal processing, our method achieves 3d point cloud detection of target velocity, range, and azimuth. Simulation results compared with traditional phase comparison azimuth measurement method proved the superiority of our method. The work and results provide suggestions to the development of vortex EM wave target detection. © 2024 Published under licence by IOP Publishing Ltd.

Vortex electromagnetic (EM) waves can provide more target information, which is orbital angular momentum (OAM), than traditional plane waves in the field of radar detection. By emitting multiple different modes of vortex EM waves to illuminate the same target, the azimuth information of the target can be obtained. The Linear Frequency Modulated (LFM) radar is often used in current OAM radar design. However, for the detection requirements of high-speed weak targets, long-term accumulation is necessary to capture the target. Due to the high-speed motion of the target, the movement of the target between different modes' echo signal cannot be eliminated after accumulation, making it difficult to compensate and extract correct target azimuth information. Therefore, this paper proposes a vortex EM wave high-speed target detection technology based on bimodal cyclic baseline. By alternately emitting vortex EM waves with OAM mode difference of 1, the mode phase information is not blurred while achieving long-term accumulation, thereby achieving distance, velocity, and azimuth detection of high-speed weak targets. Simulation results compared with traditional phase comparison azimuth measurement method proved the superiority of our method. The work and results provide suggestions to the development of vortex EM wave high-speed weak target detection. © 2024 IEEE.

The pulse based lidar currently widely used in the field of traffic monitoring has problems such as lack of precise velocity measurement ability, low ranging accuracy, and poor anti-interference performance. This article presents the design of a frequency modulated continuous wave lidar, which uses a triangular wave frequency modulation system to achieve synchronous measurement of distance and velocity information. The Doppler frequency shift compensation scheme is used to solve the coupling ambiguity problem of velocity Doppler frequency shift and distance frequency shift. The integrated design of a two-dimensional coherent laser transceiver array is used to achieve miniaturization and low power consumption of the lidar, and ultimately the implementation plan of the frequency modulated continuous wave lidar is established. The performance of frequency modulated continuous wave lidar was verified through simulation, and the results showed that it has high-precision ranging measurement ability and target three-dimensional imaging ability, which can significantly improve the detection performance and anti-interference ability of traffic monitoring lidar, and is of great significance for improving the intelligent level of traffic monitoring. © 2023 IEEE.

For the INSAR altimeter system, high precision inversion of ground elevation requires high measurement accuracy of interferometric phase. Due to the non-ideal characteristics of the hardware system and the influence of external factors such as temperature, electromagnetic interference and space radiation during the working process, the phase characteristics of the receiving link in the system will change, which is manifested as the characteristics of phase inconsistency between channels. The introduction of interference phase error will ultimately affect the high accuracy of interference measurement. In this paper, a multichannel real-time phase calibration method is proposed, which calibrates the consistency of multiple receiving links in the system through calibration links, and compensates the phase during signal processing to ensure the measurement accuracy of interference phase. © 2022 IEEE.

In order to get more detail information about targets, ultra-high-resolution (UHR) millimeter-wave radar (MMW) is widely used. UHR MMW radar is sensitive to errors, and the atmosphere effect is one of the major factors affecting the final imaging quality during the exploring of space targets. In this paper, high-precision radar signal propagation models of the background troposphere and ionosphere are established. Based on the models, the influence mechanism of the atmospheric effect on radar signal echo is investigated. The simulation results show that the tropospheric effect lead to azimuth defocusing and a large shift in the range direction on the image. The ionospheric effect produces the intra-pulse phase error which is inversely proportional to frequency. © 2021 IEEE.

Interferometric imaging altimeter is a kind of satellite-borne ocean remote sensing equipment which adopts interferometric system. It has the advantages of high resolution and high precision in sea surface height measurement, so as to realize the small and medium scale observation, fine observation and near shore observation of the ocean. In order to verify the effectiveness of the satellite-borne scheme, the flight experimentation can be used for equivalent verification. In terms of working conditions, there are differences in altitude and speed between airborne and satellite-borne. In this paper, the equivalence analysis and design are carried out from the aspects of working principle, prototype development and ground test verification, so as to realize the effective verification of the satellite-borne scheme. © 2021 SISE.
