Theory Of Operation - Harmonic Radar

The harmonic signals produced are detected by the two

receivers in SuperBroom and their respective signal strengths

displayed.

Because SuperBroom has receivers for both second and

third harmonics, and because electronic and metal non-

linear junctions give differing returns, SuperBroom is able

to provide the user with discrimination between electronic

devices and non-electronic, metallic artefacts.

Although the main application of SuperBroom is the

detection of electronic devices, this principle is employed

in some equipment to detect concealed man-made metallic

artefacts.

This method of detection is termed 'Harmonic Radar'.

In conventional Radar a radio signal is emitted which

is refl ected off a target to produce an echo at the same

frequency. SuperBroom's method of operation is to detect

echoes at harmonics of the signal emitted.

Some users refer to a Harmonic Radar as a 'Non-linear

Junction Detector'.
