Advances in ISAR processing for high resolution cross-range profiling with passive radar
2012 13th International Radar Symposium, 2012This paper presents advanced processing strategies for cross-range profiling of moving targets via ISAR (Inverse Synthetic Aperture Radar) processing in WiFi-based passive radar. In particular, it is firstly shown that the disturbance removal stage of the WiFi-based passive radar processing scheme might have a degrading effect on the quality of the ...

Time-Domain Dictionary for Sparse Representation of Radar High Resolution Range Profile
2014 IEEE 17th International Conference on Computational Science and Engineering, 2014The Dictionary is the most important basis of sparse representation which is the key issue of sparse component analysis and compressed sensing. Most of the existing dictionaries are constructed in frequency domain. This paper presented a novel dictionary constructed in time domain for radar signal representation based on geometrical theory of ...

WiFi-Based Passive ISAR for High-Resolution Cross-Range Profiling of Moving Targets
IEEE Transactions on Geoscience and Remote Sensing, 2014This paper presents an effective signal processing scheme to track moving vehicles and to obtain their cross-range profiles with a passive bistatic radar (PBR) based on the signals of opportunity emitted by a WiFi router. While the target detection using WiFi-based PBR has already been studied by the authors, this paper focuses on the targets moving ...

A Generative Approach for Incomplete High Resolution Range Profile Sequence Recognition
2019 IEEE 2nd International Conference on Electronics Technology (ICET), 2019The High-Resolution Range Profile (HRRP) sequence recognition has attracted great concern in the field of Radar Automatic Target Recognition (RATR). In this paper, a novel HRRP sequence recognition method based on Restricted Boltzmann Machine (RBM) is proposed for the poor performance of the traditional methods on incomplete data and noise corrupted ...

High resolution VHF SAR processing using synthetic range profiling
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002This paper demonstrates the use of stepped-frequency waveforms to obtain high resolution SAR images without imposing severe instantaneous bandwidth requirements on the radar system. Although azimuth compression and motion compensation are essential to obtain high resolution SAR images, this paper only discusses how to obtain high range resolutions ...

BiGRU Network for Human Activity Recognition in High Resolution Range Profile
2019 International Radar Conference (RADAR), 2019The movements of the human body result in unique radar echo changes that can be exploited for classifying human activities. In this paper, we propose a bi-directional gated recurrent neural network (BiGRU) to classify human activities based on high resolution range profiles (HRRPs).

High-resolution Range Profiles Recognition Based on SAR/ISAR Images
2019 IEEE 3rd Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC), 2019High-resolution radar range profile (HRRP) recognition has attracted a great attention for its real-time ability in imaging and processing. However, HRRP is very sensitive to aspect angle. Traditional methods, using range profile itself to create template set, require a large amount of targets’ range profiles in as many as aspect angles.

High resolution range profile statistical property analysis of radar target
6th International Conference on Signal Processing, 2002., 2003When using high resolution range profile (HRRP) to radar target identification, we must know its statistical property including the stability and separability. This paper uses six kinds of aircraft scaling model data to analyze the statistical property of HRRP in detail.

High-resolution range profile synthesis based on a new radar waveform
2016 CIE International Conference on Radar (RADAR), 2016A new waveform for high-resolution range profile synthesis with flexible bandwidth scalability is proposed in this paper. Its ambiguity function and frequency spectrum characteristics are spelled out. The signal employs a bounded function in the time domain to broaden bandwidth with time linearly.
