A system for detecting the presence,
direction, distance, and speed of aircraft,
ships, and other objects, by sending out
pulses of radio waves which are reflected
off the object back to the source.
WHAT IS RADAR?
IMAGES OF RADAR
WHAT DOES A RADAR SIGNAL
PROCESSER DO?
Distance measurement
Speed meassurement
Reduction of Interference effects
Plots and tracks
Distance measurement
Transmit time
Frequency modulation
As a part of distance measurement it measures the round trip time
for the radar to meet the target.
d=0.5(c*t)
c=speed of wave
t=time
DISTANCE MEASUREMENT
Advantages :
. Use low transmitting power, low power
consumption.
. Simple circurity, small in size.
Disadvantages :
. Several targets at a given bearing tend to
cause confusion.
. Range discription can be achieved only by
introducing very costly complex security.
. It is not capable for indicating the range of
target an can show only its velocity.
Conclusion :
. Radar signal processing is highly related with
time-frequency analysis.
. Time-frequency analysis is a powerful
technique in processing radra signal.
. A pre-modulaterwaveform in transformer and
corresponding analysis in receiver generate
arbitrary radar function.
. Other radar application:respiratory rate, size of
object…..etc.
