In a primary radar using pulse technique, the ability to discriminate between targets in azimuth is a factor of..
  • A
    aerial rotation rate.
  • B
    beam width.
  • C
    pulse recurrence rate.
  • D
    pulse length.
Refer to figure.
Optimum use of radar equipment may only be achieved with a correct set-up. Radar antennas come is various shapes and sizes, these change based on the necessary application. The antenna size governs the beam width of the pulses. In turn, the beam width greaty influences the abilities to discriminate between targets in azimuth. Narrower beams can scatter the scanned area more, whereas wider beams may detect two objects in close proximity as one reflection of pulses.
  • To discriminate between objects in azimuth: beam width must be set.
  • To discriminate in range: transmission of pulse length must be set.
