Robust Measurement-Driven Cardinality Balance Multi-Target Multi-Bernoulli Filter

open access: yesSensors, 2021
The multi-target tracking filter under the Bayesian framework has strict requirements on the prior information of the target, such as detection probability density, clutter density, and target initial position information.

Recovery of Graph Signals from Sign Measurements [PDF]

open access: yesarXiv, 2021
Sampling and interpolation have been extensively studied, in order to reconstruct or estimate the entire graph signal from the signal values on a subset of vertexes, of which most achievements are about continuous signals. While in a lot of signal processing tasks, signals are not fully observed, and only the signs of signals are available, for example

Noise Variance Estimation In Signal Processing [PDF]

open access: yes, 2007
We present a new method of estimating noise variance. The method is applicable for 1D and 2D signal processing. The essence of this method is estimation of the scatter of normally distributed data with high level of outliers. The method is applicable

Property Analysis of MIMO-Based Missile-Borne Forward-Looking SAR

open access: yesInternational Journal of Antennas and Propagation, 2014
As a special multiple-input multiple-output (MIMO) radar networking mode, missile-borne forward-looking synthetic aperture radar (MFL-SAR) has many potential applications. This paper describes and analyzes properties of this new configuration.

Towards bandwidth estimation for graph signal reconstruction [PDF]

open access: yesarXiv, 2023
In numerous graph signal processing applications, data is often missing for a variety of reasons, and predicting the missing data is essential. In this paper, we consider data on graphs modeled as bandlimited graph signals. Predicting or reconstructing the unknown signal values for such a model requires an estimate of the signal bandwidth.

3D Fully Polarimetric Attributed Scattering Center Extraction Based on Sequential 2D SAR Images

open access: yesIEEE Access, 2019
Compared with the two-dimensional (2D) attributed scattering center model (ASCM), three dimensional (3D) fully polarimetric attributed scattering center model (FP-ASCM) is able to directly offer the target location, size, and orientation in 3D space ...
