RADAR means RAdio Detection And Ranging. The RADAR sysytem
has a receiver emits either radio or microwaves that are
refelected by the target and detected by the receiver which
will be placed in the same location as transmitter.Distance
is measured by the time it takes the pulse to travel to and
from the target.Knowing the frequency the wave length is
determined by dividing the frequency in MHz into give the
wave length in meters. Radar is used in marine industries
and military application.

radio detection & ranging

Answer / basheer ali

Radar is an acronym for radio detection and ranging.
principle : radio waves (RF waves) are used to locate the
position,to find the speed, angle,& range of the target. RF
signals are generated and transmitted by the radar towards
the target.this incident energy on target is reflected in
all directions. the energy reflected in the direction of
radar is received and processed to find the information
about target.
