Simulation of high range-resolution profiles of humans behind walls
2009 IEEE Radar Conference, 2009In this paper, we present a technique for simulating time-varying, high range-resolution profiles of human motions behind inhomogeneous walls. This technique combines primitive based modeling of humans with wall simulation models generated using the finite difference time domain technique.

High resolution range profile with promoted sparsity and refined grid
IET International Radar Conference 2013, 2013A high resolution range profile (HRRP) method via compressed sensing (CS) with re-weighted 11 minimization is proposed. Since the weighted CS model has a better representation of the true sparse description than that of the general 11 norm based CS model, the proposed compressive HRRP exhibits a remarkable suppression of the noise influence when ...

In this chapter high-range resolution radar is presented. A high-resolution range profile (HRRP) is a one-dimensional signature of an object. It is a representation of the time domain response of the target to a high-range resolution radar pulse.

IEEE Geoscience and Remote Sensing Letters, 2010
In this letter, a novel radial velocity estimation and range shift compensation algorithm is proposed for high-range resolution profiling of moving targets in stepped-frequency (SF) radar. Compared to traditional methods, this algorithm is based on a more precise signal model, and can therefore achieve much higher estimation accuracy.

One dimension high range resolution profile of terahertz radar
SPIE Proceedings, 2012Step frequency signal is one of the more commonly used radar signal for high range resolution, it commonly used in radar target recognition. The wavelength of Terahertz signal is shorter than that of the microwave, so it is easy to realize the high range resolution.

Automatic target recognition using sequences of high resolution radar range-profiles
IEEE Transactions on Aerospace and Electronic Systems, 2000In this paper, we address the problem of joint tracking and recognition of a target using a sequence of high resolution radar (HRR) range-profiles. The likelihood function for the scene configuration combines a dynamics-based prior on the sequence of target orientations with a likelihood for range-profiles given the target orientation.

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 ...

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 ...
