2.  RADAR STANDS FOR RADIO
DETECTION AND RANGING
AND IT IS AN ACTIVE
TRANSMISSION AND
RECEPTION METHOD IN THE
MICROWAVE GHZ RANGE.
RADAR SENSORS ARE USED
FOR CONTACTLESS
DETECTION, TRACKING,
POSITIONING OF ONE OR
MORE OBJECTS BY MEANS
OF ELETROMAGNETIC WAVES

8. HOW MATHS IS USED IN
RADAR ?
USES OF RADAR METHOD

9. HOW MATHS IS USED IN
RADAR?
 RADAR TRANSMITS PULSES OF
MICRO RADIO WAVES , THE DISC
IS ROTATED AT A CONSTANT
RATE ABOUT A VERTICAL AXIS
SO THE BEAM SCANS ENTIRE
AIRSPACE ABOUT EVERY 5
SECONDS
 WHEN THE MICROWAVE BEAM
STRIKES SOME OF THE ENERGY
RETURNS TO THE DISC AND IT
IS DETECTED BY RADIORECIVER
SINCE THE WAVE TRAVEL AT A
CONSTANT SPEED BY
CALCULATING THE INTERVAL
BETWEEN TRANSMITTED PULSE
AND RETURNING ECHO THE
RADAR CAN CALULATE THE
RANGE FROM ANTENNA TO
OBJECT

10. WE KNOW THAT THE
VELOCITY OF RADIOWAVES IS
330M/S AND BY
CALCULATING THE TIME
INTERVAL BETWEEN
TRANSMITTED WAVE AND
RECIEVED WAVE WE CAN
CALCULATE THE DISTANCE
BETWEEN ANTENNA AND
AIRCRAFT

11. HOW IS THE DISTANCE
DETERMINED?
HOW MATHS IS USED IN
RADAR ?

12. FORMULA:
𝑑 =
𝑐 ∗ 𝑡
2
d -> DISTANCE
c -> velocity of light
t -> time taken
d
t
HOW IS THE DISTANCE
DETERMINED?

13. NEED FOR SECONDARY
RADAR?
HOW IS THE DISTANCE
DETERMINED?

14. NEED FOR
SECONDRY RADAR?
 SECONDARY RADAR IS USED BY
THE INTERROGATOR SENDING
FRQUENCY TO WHICH THE AIRRAFT
RESPOND WITH ELECTRO
MAGNETIC WAVES
 THE REPLY SIGNAL FROM
AIRCRAFT IS MUCH STRONGER
WHEN RECIVED AT GROUND
STATION THUS GIVES POSSIBLITY
OF GREATER RANGE AND
REDUCING PROBLEMS OF SIGNAL
ANNEUTATION
