Radar and Communication Spectral Coexistence on Moving Platform with Interference Suppression

Remote Sensing (2022)

Junhui Qian Ziyu Liu Yuanyuan Lu Le Zheng Ailing Zhang

With the development of intelligent transportation, radar and communication on moving platforms are competing for the spectrum. In this paper, we propose and demonstrate a new algorithmic framework for radar-communication spectral coexistence system on moving platform with mutual interference suppression, in which communication rate and the radar signal-to-interference-plus-noise ratio (SINR) are simultaneously optimized, under the energy constraints for the two systems and the radar constant modulus constraint. The radar spatial-temporal filter at the receiver and transmitting waveform are optimized, while the codebook matrix is optimized for the communication system. To cope with the established non-convex problem with triplet variables, we decouple the original problem into multiple subproblems, for which an alternating algorithm based on iterative procedures is derived with lower computational complexity. Specifically, the subproblems of communication codebook and radar filter design are convex and the closed-form solutions can be easily obtained, while the radar waveform optimization is non-convex. Then we propose a novel scheme by exploiting the alternating direction method of multipliers (ADMM) based on minorization-maximization (MM) framework. Finally, to reveal the effectiveness of the proposed algorithm in different scenarios, numerical results are provided.

An improved morphological edge detection algorithm

2022 3rd International Conference on Geology, Mapping and Remote Sensing (ICGMRS) (2022)

Zehao Yin Ziyu Liu Ming Huang

By constructing multi-scale and multi-directional structural elements and introducing Mahalanobis distance weighting coefficient, the classical morphological algorithm is improved, so as to detect the edge information of digital image with more accurate positioning, richer detail information and fluency. Firstly, three structural elements with different scales are selected for morphological opening and closing operation to remove the noise of the image; Then, the morphological edge detection is carried out by using the structural elements in four different directions: $0^{\circ}, 45^{\circ}, 90^{\circ}, 135^{\circ}$, and the edge image under the structural elements in each direction is obtained; Then the Mahalanobis distance of the edge image in each direction is calculated to determine the weight. The four images are weighted and summed according to the proportion. Finally, the edge image with ideal effect is obtained by experiment. The simulation results show that the improved morphological detection algorithm has smoother and more complete edge information, better retention of edge details, stronger anti noise performance and certain advantages.

Research on Minimum Pressure Angle of Bennett Linkage

Lele Bai Lubin Hang Xiaobo Huang Mingyuan Wang Ziyu Liu

Abstract Space deployable structures that are constructed by the single loop over-constrained linkages have been extensively applied in the fields of aerospace and construction. The pressure angle regarded as an important index to measure the performance of the basic units has attracted more and more attention. The kinematic model of the Bennett linkage is studied by the D-H matrix and the analytic formula of the pressure angle has been deducted through kinematic equations. The rule of the Bennett linkage has been discovered that the minimum pressure angle occurs while the input angle equals nπ + π / 2(n ∈ N). According to the linkage configuration at the input angle of π / 2, the geometric meaning is revealed that the minimum pressure angle of the linkage is the same as the twist angle of the joint axes of the output link. Finally, conclusions can also be drawn that the smaller the twist angle of the output link is, the smaller the minimum pressure angle will be. The research enriches the kinematics of Bennett linkage and provides a reference for its engineering applications.
