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 …

The conventional radar technology is based on linear detection—ie, the same transmit and
receive frequencies are used. However, with linear radars, difficulties arise when detecting …

This paper introduces a new maritime search and rescue system based on S-band
illumination harmonic radar (HR). Passive and active tags have been developed and tested …

Nonlinear radars can be utilized to detect electronic devices, which are difficult to detect with
conventional radars due to their small radar cross sections (RCS). Since the receiver in a …

This paper describes the development of a new 3D ground-penetrating radar (GPR)
acquisition and control technology for road underground diseases with dual-band antenna …

Nonlinear radar exploits the difference in frequency between radar waves that illuminate
and are reflected from electromagnetically nonlinear targets. Harmonic radar is a special …

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 …

Nonlinear radars are often used to detect the presence of RF electronics. In the state-of-art
most of researchers has chosen to exploit the second-harmonic response of target. But its …

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 …

Much literature relevant to nonlinear junction detection and harmonic radar discusses
tracking of nonlinear tags. Those tags are designed to generate particular response …
