An extensive review of nonlinear radar systems is performed. Emphasis is placed on
designs relevant to detecting RF electronics that were not intentionally manufactured as …

This article presents a frequency-modulated continuous wave (FMCW) harmonic radar in the
61-/122-GHz industrial, scientific, and medical (ISM) frequency bands. The radar is based on …

In this article, fully integrated binary phase shift keying (BPSK) tags are presented to work in
conjunction with narrowband frequency-shift keying (FSK) radar for concurrent multitarget …

Although traffic safety continues to improve overall, fatalities of vulnerable traffic participants
and pedal cyclists specifically have reached 30-year highs. While automotive radar sensors …

This paper details the design and implementation of a harmonic frequency-modulated
continuous-wave (FMCW) radar system, specialized in detecting harmonic tags and …

Data about users is collected constantly by phones, cameras, Internet websites, and others.
The advent of so-called 'Smart Things' now enable ever-more sensitive data to be collected …

Traffic incidents involving vulnerable road users (VRUs) constitute a significant proportion of
global road accidents. Advances in traffic communication ecosystems, coupled with …

A broad review of publications relevant to nonlinear radar is conducted. The principle-of-
operation of nonlinear radar is summarized and applications for this technology are listed …

This paper introduces a novel way to implement passive RF identification (RFID) at
millimeter waves. Passive operation is achieved by adding an external mixing element …

Smart home electronic devices invisibly collect, process, and exchange information with
each other and with remote services, often without a home occupants' knowledge or …
