Target's optimal polarization is the fundamental theory of radar polarization. Null-Pol, also called Co-Pol Null, is one of the significant polarization states, through which other optimal polarization states can be derived. Null-Pol theory is widely applied in polarization reception match, contrast enhancement and so on. This paper revealed the advantage of Null-Pol theory in manmade target scattering structure recognition for the first time. The complex polarization ratio plane and polarization response characteristics were combined and the Null-Pol 3D response patterns were represented, which can reveal the difference of canonical scattering structures. Then, the Null-Pol scattering structure recognition method of manmade targets is proposed. The scattering centers are extracted from radar images. The scattering structure type can be identified by matching the Null-Pol response characteristic vectors with canonical scatters. Through the analysis of electromagnetic computation data of manmade targets, the proposed Null-Pol scattering structure recognition method can identify the scattering structure types of manmade targets. Especially, the results of symmetric targets have better performance than Cameron decomposition, which is more consistent with target's actual scattering structure types. © 2021 IEEE.

In this work, the non-cooperative target localization problem in the outdoor environment is addressed, which suits the non-line-of-sight (NLOS) scenario. Localization accuracy is highly affected by non-cooperative source and multipath phenomena, making the problem harder to handle. A non-cooperative target situation cannot obtain the time of arrival (TOA). Therefore, traditional precise positioning methods fail in this scenario. Thence, to handle the localization problem at adverse conditions, this paper takes the angle of arrival (AOA) into account. Considering the channel reciprocity between transceivers, a novel localization method is proposed by combining AOA and ray-tracing (RT). Besides, a density-based clustering algorithm is used to enhance localization accuracy. Our simulation validates the correctness and effectiveness of the proposed approach, outperforming the fingerprint (FP) localization method and showing the hybrid algorithm's benefit. © 2021 IEEE.

Ray tracing model as a deterministic model in the prediction of radio waves propagation has the advantages of fast operation and accurate prediction. However, its accuracy depends on the preset electric parameters, especially for complex indoor environment, the relative dielectric constant and conductivity of the wall is particularly important to the model. Therefore, an electric parameter optimum algorithm is needed to use for model calibration. In this paper, an indoor scene of an apartment is taken as an example. Based on the measured power value, a feedback step search method is used to correct the electrical parameters of wall material, so that the corrected model can predict the power of this particular scene more accurately. © 2021 IEEE.

Based on the idea of tightly coupled dipole array, a low profile, broadband circularly polarized array is designed in this paper. The circularly polarized phased array element consists of dual polarized dipoles with the same phase center and orthogonal arrangement, grounded coupling patches, resistive frequency selective surfaces (RFSS), and a 90° phase shifter network. In order to realize broadband scanning, the effect of RFSS on the input active voltage standing wave ratio and radiation axial ratio (AR) of the element is studied. The results show that the element can operate at 5-11.5GHz, within a ±45° angle scanning range, the AR of each scanning plane is less than 3dB, and the profile height is only 0.33 ? high. © Published under licence by IOP Publishing Ltd.

We present an efficient method to simulate the average K-factor in a reverberation chamber (RC). The proposed method is based on the duality between absorption and scattering of electromagnetic waves in an RC. By replacing the rotating stirrers with absorbers, the average K-factors can be estimated quickly. Compared with the direct simulation, the proposed method is very efficient and is 15 times faster. © 2022 IEEE.

In this paper, an adjustable active frequency selective surface (AFSS) with polarization insensitive properties is proposed. The designed structure comprises an active impedance layer, a dielectric layer, and a metal backplane layer. The active impedance layer contains '' - shaped structural unit, whose modulating properties are realized by controlling pin diodes. The switchable bandwidth of the proposed structure can achieve an adjustable effect of less than -15dB and covers a much wider frequency band (8.8-11.8GHz and 12.6GHz-18.6GHz) compared with previous adjustable AFSS reflector. Meanwhile, the structure is suitable for the two polarization states of TE and TM due to the symmetry of the unit structure. Finally, the CST simulation is carried out to demonstrate the validation of proposed structure. © 2021 IEEE.

Radar Polarimetric information can effectively expand the understanding of target shape and structure, and have potential of exploring materials and local fine features of targets. In this paper, based on the theory of coherent and incoherent polarimetric decomposition, we extract features of multiple types of unmanned aerial vehicles with full polarization. Then communication with local agents (CLA) method is used to overcome shortcomings of difficulty of obtaining target training samples under real electromagnetic environment conditions. Based on the extracted polarimetric scattering mechanism, we can realize the accurate identification of UAVs without training samples. The validity of the proposed algorithm is verified based on electromagnetic data measured in anechoic chamber and calculated by the software. The experiment proves that the recognition rate of the proposed algorithm is higher than that of conventional algorithms, and it has the ability to characterize the fine structure of unmanned aerial vehicles. © 2021 IEEE.

Polarization plays an important role in analyzing radar targets. Full polarization information has a better ability to inverse fine structures of the target. However, previous studies of high-resolution range profile (HRRP) mainly neglected effects of polarization. Therefore, a novel radar target recognition algorithm based on accelerated t-Distributed Stochastic Neighbor Embedding(t-SNE) and multi-polarization weighted fusion has been proposed. Firstly, three single polarization channels, odd and even-bounce mechanism HRRP, and full polarization HRRP are described. The accelerated t-SNE method based on Barnes-Hut approximation improves the dimensionality reduction speed of processing HRRPs while maintaining the initial information of each HRRP. Also, it is capable of visualizing different targets. With the weighted fusion of posterior probabilities of multiple support vector machines (SVMs), we are able to realize recognition of targets. Experimental results of vehicle targets based on electromagnetic calculations show that recognition performance of this algorithm is superior to other methods, and it shows strong robustness under the condition of large azimuth angle. © 2021 IEEE.

With the development of depth learning and synthetic aperture radar (Synthetic Aperture Radar, SAR) technology, SAR image target detection based on convolution neural network (convolutional neural network, CNN) has achieved certain results. However, there are still problems in SAR detection of near-shore ship targets in complex environments. For improving the detection performance of the algorithm, the detection rate of SAR image near shore ship targets in complex environment is improved. This paper proposes an algorithm for SAR image ship target detection in complex environment. The algorithm first uses convolution neural network for coastal segmentation, and SAR image ship target detection through the results of coastal segmentation. The experimental results show that the algorithm has efficient detection ability for SAR image near-shore ship target detection in complex environment. © 2021 IEEE.
