An Efficient ISAR Imaging of Targets with Complex Motions Based on a Quasi-Time-Frequency Analysis Bilinear Coherent Algorithm

open access: yesSensors, 2018
The inverse synthetic aperture radar (ISAR) imaging for targets with complex motions has always been a challenging task due to the time-varying Doppler parameter, especially at the low signal-to-noise ratio (SNR) condition.

Object identification and tracking by quantum radar

open access: yesQuantum Technologies and Quantum Information Science V, 2019
Quantum Radar is a promising technology that could have a strong impact on the civilian and military realms. In this study we introduce a new concept design for implementing a Quantum Radar, based on the time and polarization correlations of the entangled photons for detection and identification and tracking of high-speed targets. The design is focused

V2V Communications in Automotive Multi-sensor Multi-target Tracking [PDF]

open access: yes, 2008
Today’s automotive sensor systems for in-vehicle based target tracking, i.e. radar, lidar, camera, are limited to a field of view which is restricted by distance, angle and line-of-sight.

Life-Long Radar Tracking of Bumblebees

open access: yesPLOS ONE, 2016
Insect pollinators such as bumblebees play a vital role in many ecosystems, so it is important to understand their foraging movements on a landscape scale. We used harmonic radar to record the natural foraging behaviour of Bombus terrestris audax workers over their entire foraging career.

Developments in target micro-Doppler signatures analysis : radar imaging, ultrasound and through-the-wall radar [PDF]

open access: yes, 2013
Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Radar Selection Method Based on an Improved Information Filter in the LPI Radar Network

open access: yesInternational Journal of Antennas and Propagation, 2018
In order to save the radar resources and obtain the better low probability intercept ability in the network, a novel radar selection method for target tracking based on improved interacting multiple model information filtering (IMM-IF) is presented ...

Joint Transmit Resources and Trajectory Planning for Target Tracking in Airborne Radar Networks

open access: yesLeida xuebao, 2022
This paper investigates the joint optimization problem of transmit resources and trajectory planning for target tracking in airborne radar networks. First, the analytical expression for the Bayesian Cramér-Rao Lower Bound (BCRLB) with the variables of ...

Tracking bees with radar

open access: yesBee World, 1999
The flight patterns of bees have been studied for over 100 years, but due to their small size, bees can only be tracked by eye for a very short distance from the nest or hive. Scientists have employed various techniques, including mark-recapture, feeder experiments, homing experiments and the interpretation of bee dances, to investigate bee foraging ...

Tracking of ground targets with bistatic airborne radar

open access: yes, 2022
6 S.Detection of moving targets in stationary clutter can be accomplished by STAP radar. In contrast to monostatic radar the performance of bistatic STAP depends strongly on the actual radar-target geometry. Even for sidelooking radar the clutter Doppler
