Radio frequency identification (RFID) has gained significant attention because it provides a
highly versatile platform for identifying, tracking, and monitoring objects. An emerging trend …

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 …

Responding to the critical need for stable microwave absorption (MA) devices in complex
and extreme environments, dual-function electromagnetic wave absorbers have garnered …

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

One-bit quantization technique is able to lower power consumption, save storage space,
and reduce system cost, which, when tailored for radar sensing, is applicable to small-size …

In harmonic radar (HR), the transmitter illuminates a nonlinear target (the tag), causing the
return signal to consist of harmonics at multiples of the transmitted carrier frequency. Of …

Aiming the extract micro-motion features of rotor targets when the flashes are in the echo,
this paper proposes a method based on the GS-IRadon algorithm. At first, we analyze the …

A new method for detecting microwave harmonic Doppler signatures of held objects in
cluttered environments is presented. Based on a passive harmonic tag combined with a …

When an electromagnetically-nonlinear radar target is illuminated by a high-power stepped-
frequency probe, a sequence of harmonics is unintentionally emitted by that target …
