Measurements and analysis of the radar cross section of chaff dipoles

IET Radar, Sonar & Navigation
A free space test method to measure the Radar Cross Section (RCS) of single dipole elements is presented. The method is such that dipoles can be measured over a large range of frequencies, in free space and without the need of an anechoic chamber.

Electronic Countermeasure System for Jamming

International Journal for Research in Applied Science and Engineering Technology
This project focuses on designing and constructing a compact portable electronic jammer operating in the 2.4 GHz frequency range which covers the bands for other technologies such as Wi-Fi or Bluetooth for wireless communication. The system architecture is based on ESP32 microcontrollers and nRF24L01 RF transceivers that are used to create signals that

Defeating angle tracking: A comprehensive analysis of scan rate modulation jamming against sequential lobing radars

IET Radar, Sonar & Navigation
The authors analyse the sequential lobing radar (SLR) resistance against the scan rate modulation (SRM) jamming technique. Unlike previous studies, the authors analyse SLRs with sinc antenna patterns, enabling investigation of the sidelobe region's ...
