Adaptive Mainlobe Interference Suppression in Sparse Distributed Array Radar Based on Synthetic Wideband Signal 2nd

引用

2nd International Conference on Machine Learning and Intelligent Communications, MLICOM 2017

作者： Luo, Jian Zhang, Honggang Song, Yuanyuan Beijing Key Laboratory of Embedded Real-Time Information Processing Technology Radar Research Laboratory School of Information and Electronics Beijing Institute of Technology Beijing100081 China

This paper proposes a mainlobe interference suppression method in distributed array radar (DAR) based on stepped frequency synthetic wideband signal. Due to the equivalent large aperture of DAR, it is possible to cancel the mainlobe interference without target signal suppression. The applying of stepped frequency synthetic wideband signal can avoid the different time delays arriving at each array compared with the traditional instantaneous wideband Chirp (linear frequency modulation) signal. Moreover, it can reduce the computational complexity. This method employs the narrowband adaptive processing to each sub-pulse of the stepped frequency signal, and then synthesizes the high resolution range profile (HRRP). As a result, mainlobe interference suppression under wideband signal is accomplished. Mainlobe interference suppression experiment is carried out by using an S-band experimental radar system, an S-band noise jammer and a target simulator. The measured data is processed employing the proposed method, and the result verifies the effectiveness of this algorithm. © 2018, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

In this study, a single channel pipelined variable-length fast Fourier transformation (FFT) processor design is presented. With the development of science and technology, digital signal processing has been widely used in many fields. The most basic algorithm of digital signal processing theory, FFT, is widely used in radar signal processing, remote sensing, image processing, communications and other fields. A high real-time and high-throughput FFT processor design method based on the field-programmable gate array (FPGA) platforms is proposed to meet the needs of the synthetic aperture radar imaging digital signal processing. The authors conducted the ISE synthesis based on the Xilinx FPGA platform using xc6vlx760ff1760-1 as the target chip and the ModelSim simulation, combined with Matlab, to verify the correctness of this design. © 2019 Institution of Engineering and technology.

Aerial animal migration is closely related to human life, and radar is one of the most effective means of observing it. However, scanning radar has a low data rate, a short integration time, and lacks prior knowledge of target speed, while migratory animals exhibit high mobility. These factors make traditional tracking filter algorithms ineffective at predicting their movement. To address this issue, this paper proposes a tracking filter algorithm based on group dynamics constraints, leveraging the characteristic behavior of migratory animals flying in groups. First, the dynamic state of the group is calculated using the group as the research unit. Then, tracking filtering is performed under the constraint of group dynamics. Simulation and field data have verified the effectiveness of the proposed algorithm. © 2024 IEEE.

2018 China International SAR Symposium, CISS 2018

作者： Zhou, Zhichao Ding, Zegang Zhang, Tianyi Wang, Yan Radar Research Lab School of Information and Electronics Beijing Institute of Technology Beijing Key Laboratory of Embedded Real-time Information Processing Technology Beijing China

For high velocity motion platform, it usually takes a shorter azimuth accumulation time to achieve high-squint synthetic aperture radar (SAR) imaging for noncooperative moving ship target with meter-level resolutions. In this case, three-dimensional relative motion of the ship target can be neglected approximately, mainly the translational motion should be considered. However, the magnitude and direction of the target's translational velocity are unknown. To solve the above problem, a two-step imaging method is proposed in this paper. Firstly, the entire scene is coarsely imaged by using the parameters provided by inertial navigation system. The position of the ship target can be judged by two-dimensional order statistics constant false alarm rate (OS-CFAR) detection and ship target pixel clustering. By constructing the band-pass filter in azimuth frequency domain, the data of the target can be obtained effectively, and to a certain extent, sea clutter and noise are suppressed. Then the motion parameters are estimated. Finally, the target is secondarily imaged with the estimated parameters to achieve precise focus. The results of simulation verify the correctness of the analysis and the validity of the proposed method. © 2018 IEEE.

The fast Fourier transform FFT processor is an important part of the space real-time signal processing system based on field programmable gate array (FPGA). Since occupying a large amount of logical resources and storage resources, FFT processor is more vulnerable to high-energy particles in space, resulting in single event upset (SEU). This paper presents a novel FPGA scrubbing framework base on dynamic partial reconfiguration technique for a FFT processor to mitigate SEU. The proposed scheme is compared with the blind scrubbing, the reconfiguration time is reduced by 78%. Then, the resource utilisation is 61.5% less than triple modular redundancy scheme. This paper also presents a DPR controller for FFT processor, which is evaluated in terms of hardware resources and reconfiguration time. A comparison to the Xilinx PRC IP shows that multipath delay feedback FFT controller saves 38.6% resources. © 2019 Institution of Engineering and technology. All rights reserved.

Radar network has important application in many fields, such as small target detection etc, especially for the case with wide baseline. Until now, the research to the 3-dimensional (3D) target localization accuracy using radar network is still a research focus in the radar community. In this paper, further research to the radar network with aerial and ground-based nodes is carried out, and the analytical expression of 3D target localization accuracy is derived using the Cramer-Rao lower bound (CRLB). Based on the analytical formulae, impacts of the system topology on the target localization accuracy are investigated. Finally, numerical simulations verify the theoretical analysis of the results.. © 2017 DGON.

Long-time integration is an effective method to improve the signal-to-noise ratio (SNR) and detection performance of highly maneuvering targets. The existing methods for long-time integration mainly focus on detecting targets with high-order motion under fixed model, losing sight of the possibility that targets may have an abrupt motion change at an unknown instant. Therefore, this paper proposes a novel long-time integration method for highly maneuvering target with abrupt change model (ACM) based on generalized Radon-Fourier transform (GRFT), which could coherently integrate the target echoes before and after ACM and obtain the optimal coherent integration gain. The simulation and experiment results show that the proposed method can detect the ACM target under the condition of extremely low SNR and improve the detection performance compared with the fixed model GRFT. © 2019 IEEE.

IET International Radar Conference 2015

Frequency Modulated Continuous Wave (FM-CW) waveform has been widely used in radar range measuring, speed measuring and imaging. However, the performance of matched filtering for range compression is usually degraded by the nonideal factors in the real radar system, such as the frequency modulation ratio error and the unstable sampling clock. In this paper, an iterative method is proposed to compensate these phase errors induced by the nonideal factors based on the entropy minimum. The principle of the proposed iteration is to construct a series of local quadratic curves to gradually approach the minimum. Finally, both simulated and experimental datasets are used to validate the feasibility and effectiveness of the proposed method.

2nd IEEE International Conference on Signal, information and Data processing, ICSIDP 2024

In the field of target detection, infrared small target detection(ISTD) is a critical area of research, playing a vital role in reconnaissance, guidance, and early warning systems. Existing spatial Filtering algorithms perform well in clean backgrounds;however, as these filters require manual design based on prior knowledge, they are prone to interference from complex scenes (e.g., clouds, buildings), leading to target omission. Small targets typically exhibit blurry features and weak energy, making direct detection susceptible to interference from high-intensity areas, which may result in missed detections. To tackle these challenges, this paper presents a two-tier contrast improvement method (DLCE). First, a gradient filter group is used to enhance the signal-to-noise ratio (SNR) of the target, and then, built upon the concept of local contrast measurement (LCM), a novel intensity calculation method is developed. The new contrast window design effectively enhances the target's SNR. Compared with existing algorithms, like MPCM (Multi-Scale Patch-based Contrast Measurement) on publicly available datasets, the proposed method more effectively enhances the target's radiative intensity while suppressing background noise. The effectiveness of the proposed algorithm is confirmed by the simulation results. © 2024 IEEE.
