Generalized Radar Range Equation Applied to the Whole Field Region

open access: yesSensors, 2022
Most terahertz (THz) radar systems can only work in the near-field region, because the THz source power is limited and the size of the target scattered near field is up to tens of kilometers.

Radar Cross Section Near-Field to Far-Field Prediction for Isotropic-Point Scattering Target Based on Regression Estimation

open access: yesSensors, 2020
Radar cross section near-field to far-field transformation (NFFFT) is a well-established methodology. Due to the testing range constraints, the measured data are mostly near-field.

In‐band radar cross‐section reduction of the slot array antennas by RAM‐based frequency selective surfaces

open access: yesIET Microwaves, Antennas & Propagation, 2021
A method for reducing radar cross‐section (RCS) of the slot array antenna by utilising the radar absorbing material, while preserving the radiation performance simultaneously, is proposed and discussed.

Design and Implementation of Radar Cross-Section Models on a Virtex-6 FPGA

open access: yesJournal of Engineering, 2014
The simulation of radar cross-section (RCS) models in FPGA is illustrated. The models adopted are the Swerling ones. Radar cross-section (RCS) which is also termed as echo area gives the amount of scattered power from a target towards the radar.

Classification of Radar Targets with Micro-Motion Based on RCS Sequences Encoding and Convolutional Neural Network

open access: yesRemote Sensing, 2022
Radar cross section (RCS) sequences, an easy-to-obtain target feature with small data volume, play a significant role in radar target classification. However, radar target classification based on RCS sequences has the shortcomings of limited information ...

Insect ventral radar cross-section polarisation dependence measurements for radar entomology [PDF]

open access: yes, 2006
Radar entomology has developed such that routine long-term monitoring of insect flight through the atmospheric boundary layer is now practical. Typical entomological radars use X-band (9.4 GHz) marine transceivers with a vertical pencil beam and rotate ...
