This study presents a highly efficient power amplifier (PA) based on a compact harmonic-
controlled matching network (HCMN). The proposed HCMN with three-stage band-stop …

A design for frequency-selective radio frequency (RF) harmonic tags for harmonic Doppler
radar tracking is presented. Harmonic RF tags receive an incident microwave signal and …

Nonlinear radar has a unique advantage in finding nonlinear targets, like radio frequency
(RF) electronics and harmonic tags, under clutter circumstances, among which …

The properties of Doppler through-wall radar (TWR) in target localization applications mainly
depend on the accuracy of instantaneous frequency (IF) estimations obtained from the time …

In this study, a highly efficient harmonic suppressed dual-band power amplifier (PA) for
harmonic radar systems is proposed. The proposed PA incorporates a harmonic-controlled …

This paper proposes a system for detecting and classifying realistic electronic devices in the
presence of linear clutter objects based on a frequency-modulated con-tinuous-wave …

We demonstrate the classification of common motions of held objects using the harmonic
micro-Doppler signatures scattered from harmonic radio-frequency tags. Harmonic tags …
