Spectrally Compatible Deceptive Jamming Waveform Design for Synthetic Aperture Radar Countermeasures
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper focuses on the design of synthetic aperture radar (SAR) deceptive jamming waveforms with spectrumâcompatible capability. By using the synthesised jamming waveform, successful deception against the hostile SAR system is demonstrated by generating false targets with high fidelity in both range and azimuth.

A New Approach to Iterative Clipping and Filtering PAPR Reduction Scheme for OFDM Systems
IEEE Access, 2018 While achieving reduced/good peak-to-average power (PAPR) in orthogonal frequency division multiplexing (OFDM) systems is attractive, this must not be performed at the expense of the transmitted signal with over-reduced signal power, as it leads to ...
