WiFi-Based Passive ISAR for High-Resolution Cross-Range Profiling of Moving Targets

IEEE Transactions on Geoscience and Remote Sensing, 2014
This 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 ...

High resolution VHF SAR processing using synthetic range profiling

IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002
This 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), 2019
The 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).

An Efficient Kernel Optimization Method for High Range Resolution Profile Recognition

2006 CIE International Conference on Radar, 2006
A kernel optimization based on fusion kernel for HRRP is proposed in this paper. Based on the fusion of the 1-norm and 2-norm Gaussian kernels, our method combines the different characteristics of them so that not only is the kernel function optimized but also the speckle fluctuations of HRRP are restrained.

High Resolution Range Profile Analysis in an OFDM Integrated Radar-Communication System

2018
Due to the data transmission requirements in traditional orthogonal frequency division multiplexing (OFDM) radars, the phase-coded OFDM (PC-OFDM) waveforms in which the PC sequence is controlled via transmitted messages are presented for radar-communication integrated applications.
