ATO test 2 Exam Questions and Answers
Search radar - -Continuously scans a volume of space and provides initial
detection of all targets.
- Tracking radar - -Provides continuous positional data on a target. Used for
fire control.
- Middle guidance radar - -Provides information used to guide a missile.
- Approach radar - -Guides aircraft to a safe landing u see zero visibility.
- Ground controlled approach - -Land based.
- Carrier controlled approach - -Movement of the ship.
- Airborne radar - -Designed specifically to meet strict space and weight
limitation.
- Pulse modulation - -Transmitted in very short bursts called pulses. 1
micro.sec- 50 micro.sec.
- Frequency modulation - -Transmits frequency waves that are continually
increasing and decreasing from a fixed point.
- Continuous wave - -Operates on the principles of Doppler effect.
- Pulse Doppler - -Modification of a pulse radar system using Doppler effect
to detect moving targets.
- Range measurements - -Measures the elapsed time during which emitted
pulse travels to the target and returns. 12.36 micro.sec
- Minimum range - -Determined by the time of the transmitter pulse.
- Max range - -Depends upon carrier frequency, peak power, prf, and
receiver sensitivity.
- Range resolution - -separation in range of two targets on the same
bearing.
- Azimuth resolution (bearing) - -Ability to separate targets at the same
range but different bearings.
- Slant range - -Range measurement of a difference in altitude.
