Hi friends, every one who knows about electronics devices
will be familiar with diode and optical sources like LASER and LED. The optical
sources are also diodes. By knowing this every one may think that why a normal
diode could not emit light where as a LASER and LED does?
The answer to this question lies in developing of these
normal and optical diodes.
The major differences between normal and LASER and LED type of...
Introduction to RADAR Systems.
Saturday, 18 January 2014
RADAR is
abbreviated as Radio detection and ranging. Radar is an electromagnetic system,
which generates EM signals to detect and to find the distance from system to objects
(or) targets near to it.
How it can
detect?
As said
earlier radar transmits the EM signal from an antenna, these signals spread out
in space and when they hit any object they come back to receiver, present in
the same antenna. Returned signal is called...
