Military Radar

  1. 1. WHAT IS RADAR ?? • RAdio Detection And Ranging • An Object Detection System that transmits the electromagnetic waves and analyzes the echoes coming from the objects • German inventor Christian Hülsmeyer built a simple ship detection device intended to help avoid collisions in fog which worked in a short distance
  2. 2. Basic Parts and Design of RADAR • Transmitter • Duplexer • Receiver • Radar Antenna • Indicator
  3. 3. RADAR EQUATION The power Pr returning to the receiving antenna is given by the equation: (PtGtArσF4) (4π)2R4 ___________Pr=
  4. 4. DIFFERENT KIND OF RADARS. Simple Pulse Radar
  5. 5. Moving‐Target Indication (MTI) Radar DIFFERENT KIND OF RADARS.
  6. 6. DIFFERENT KIND OF RADARS. Pulse Doppler radar
  7. 7. DIFFERENT KIND OF RADARS. Tracking Radar
  8. 8. Frequency-modulated Continuous-wave (FM-CW) Radar: DIFFERENT KIND OF RADARS.
  9. 9. APPLICATION OF RADAR IN DEFENCE FIELD Air defense radars Ground Surveillance Radar Missile Control Radar Navigational based Radars Air Traffic Control Radar
  10. 10. ADVANTAGES OF MILITARY RADARS • All-weather day and night capability. • Multiple target handling and engagement capability. • Short and fast reaction time between target detection and ready to fire moment. • Easy to operate and hence low manning requirements and stress reduction under severe conditions • . • Highly mobile system, to be used in all kind of terrain • Flexible weapon integration, and unlimited number of single air defence weapons can be provided with target data.
  11. 11. • Time - Radar can take up to 2 seconds to lock on • Radar has wide beam spread (50 ft diameter over 200 ft range). • Cannot track if deceleration is greater than one mph/second. • Large targets close to radar can saturate receiver. • Hand-held modulation can falsify readings. DISADVANTAGES
  12. 12. CONCLUSION Military radars are one of the most important requirements during the wartime, which can be used for early detection of ballistic missile and also for accurate target detection and firing. Radar system discussed here has a built in threat evaluation program which automatically puts the target in a threat sequence, and advises the weapon crew which target can be engaged first.
