Height Measurement for Meter-wave MIMO Radar Based on Block Orthogonal Matching Pursuit Preprocessing

open access: yesLeida xuebao, 2020
Meter-wave radar has good anti-stealth performance. The waveform diversity of Multiple-Input Multiple-Output (MIMO) radar can result in a higher degree of freedom, which makes MIMO radar more advantageous in detection and parameter estimation. Therefore,

Target detection approach for DRM-based passive bistatic radar

open access: yesThe Journal of Engineering, 2019
This study discussed the problem of target detection for digital radio mondiale (DRM)-based passive bistatic radar (PBR). In the surveillance signal, the power of zero Doppler contribution (ZDC) is stronger than the echoes of weak targets.

Shadow Effect for Small Insect Detection by W-Band Pulsed Radar

open access: yesSensors, 2023
In radar entomology, one primary challenge is detecting small species (smaller than 5 cm) since these tiny insects reflect radiation that can be poorly observable and, therefore, difficult to interpret. After a literature search on radar entomology, this

Weather surveillance radar as an objective tool for monitoring bat phenology and biogeography

open access: yesThe Journal of Engineering, 2019
Bats provide a wealth of vital services to humans, such as pollinating plants and managing populations of insects that act as agricultural pests and disease vectors. Despite their direct importance, it is inherently difficult to monitor bats across large
