POLSAR Target Recognition Using a Feature Fusion Framework Based on Monogenic Signal and Complex-Valued Nonlocal Network

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
With the continuous development of synthetic aperture radar (SAR) systems, multipolarization information has been increasingly applied to numerous fields, and automatic target recognition (ATR) in polarimetric SAR (POLSAR) has been recognized as vital ...

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.

Optimised multi-hypothesis tracking algorithm based on the two-dimensional constraints and manoeuvre detection

open access: yesThe Journal of Engineering, 2019
With the increase of target mobility and environment complexity, highly reliable single-period statistical judgments become more and more difficult. The multiple hypothesis tracking (MHT) algorithm is a method based on delay logic, and can effectively ...

Deinterleaving method of complex staggered PRI radar signals based on EDW fusion

open access: yesThe Journal of Engineering, 2019
Most of the existing pulse deinterleaving algorithms cannot deal well with complex staggered pulse repetition interval (PRI) radar signals which have >10 stagger levels.

Using Radar Cross-Section to Enhance Situational Awareness Tools for Airport Avian Radars

open access: yesHuman-Wildlife Interactions, 2017
Digital avian radars can track bird movements continuously in the vicinity of airports without interruption. The result is a wealth of bird-track data that can be used in mitigation efforts to reduce bird strikes on and near airfields.

MIMO noise radar - matched filters and coarrays [PDF]

open access: yes, 2008
Copyright © 2008 IEEEThe noise radar concept can be extended to an array of K transmit antenna and M receive antenna. When independent noise sources are transmitted from each antenna the approach may be viewed as a special case of MIMO radar and matched ...

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

open access: yes, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Examination of the effect of array weighting function on radar target detectability [PDF]

open access: yes, 2010
This paper describes a methodology to assess the detectability of targets by anairborne fire control radar operating in a medium PRF mode in the presence of strongground clutter as a function of the transmitting and receiving antenna array ...
