Question

Which of the diode is used as detector in a radar.​

Answer 1

${\huge{\underline{\boxed{\mathfrak{\blue{A}\green{n}\purple{s}\blue{w}\green{e}\purple{R::}}}}}}$

A Schottky diode is used in detection circuit in this case. The principle of diode detection is rectifying the signal (AC component) through a diode and generating voltage as DC component. The detection makes use of the non-linear characteristic of the Schottky diode, so a bias circuit is not necessary.

____________________________________

Extra::

In many instances Schottky diodes are used for this form of detector, because signal levels may be low, and Schottky diodes have a much lower turn on voltage (typically around 0.2 V) than standard silicon diodes (typically around 0.7 or 0.7 V).

Answer 2

Schottky Diode Detector

• The applications that use the principle of Schottky Diode Detector, SDD, are varied and touch several domains. 

• Radar system is one of these applications where SSD appears especially interesting and gives a strong renewal of gain.
