Space-time percolation and detection by mobile nodes [PDF]

open access: yes, 2015
Consider the model where nodes are initially distributed as a Poisson point process with intensity $\lambda$ over $\mathbb{R}^d$ and are moving in continuous time according to independent Brownian motions.

Moving target detection in clutter background with FDA-MIMO radar via three-dimensional focus processing

open access: yesThe Journal of Engineering, 2019
Low observable moving target-detection technology under clutter background is the key factor affecting the radar performance. Here, frequency diverse array (FDA) MIMO radar is investigated for low-observable moving target detection.

Improvement in detection with forward scattering radar [PDF]

open access: yes, 2011
Forward scattering radar (FSR) has advantages over traditional monostatic radar such as an enhanced radar cross section. Enhancement of the radar cross section can increase the detection range of the FSR system.

Moving Target Shadow Detection Method Based on Improved ViBe in VideoSAR Images

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The video synthetic aperture radar (VideoSAR) has the high frame-rate imaging capability, which can perform the ground moving target detection. The moving target often leaves the shadow in the sequence of the VideoSAR images, which can indirectly detect ...

Adaptive Radar Detection of Dim Moving Targets in Presence of Range Migration

open access: yes, 2019
This paper addresses adaptive radar detection of dim moving targets. To circumvent range migration, the detection problem is formulated as a multiple hypothesis test and solved applying model order selection rules which allow to estimate the "position ...

Innovative Multi-Target Estimating with Clutter-Suppression Technique for Pulsed Radar Systems

open access: yesSensors, 2020
Linear frequency modulation (LFM) waveforms have high Doppler-shift endurance because of the relative wide modulation bandwidth to the Doppler variation. The Doppler shift of the moving objects, nevertheless, constantly introduces obscure detection range
