ATO test 6 Exam Questions with
Answers
Pulse - -Used to detect and track targets on a RANGE BASIS.
- Pulse Dopplar - -Used to detect and track targets on a velocity basis.
- Continuous Wave - -Used to illuminate the target with CW RF energy and
provide missile INTERCEPT guidance for SPARROW MISSLE.
- Dual Waveguide Feedhorn - -Two back to back waveguide sections which
act as a SINGLE WAVEGUIDE during xmit.
- Auxiliary Horn - -Used for tracking through angle deception jamming.
- Beam Spoiler Plate - -Changes the main love beam pattern during air to air
surface operation.
- Waveguide System - -Delivers high power RF energy from the pulse, pulse
Doppler, or CW to antenna.
- Waveguide System - -Receives pulse or pulse Doppler target return.
- Test Circuits - -Checked by digital BIT capability for radar and missile
firing.
- Mode Track and Switching Circuits - -Allows selection of SEAM and
following modes.
- Antenna Control - -Allow switching from search to acquisition and
ultimately to track.
- Modes of Operation - -Pulse, H map, L map, A/G, PD, CDI
- H Map - -High altitudes.
- FDI Freeze Displayed Impact - -Used for missile launch info for sparrow,
sidewinder, and air to air.
- Short Pulse - -Short range
- Chirp - -Used for long range target detection 28.5-31.5 MHz
- Range Selected - -25 and 50mi= 100Hz
, 100mi=600Hz
200mi=300Hz
- Mono Pulse Operation - -Used in the A/G mode PRF of 3000Hz and pulse
width of .2 microsecond
- Pulse Dopplar Operation - -PRF is varied continuously except during track
condition.
- Pulse Dopplar Operation - -WS provides true heading to the fire control
system
- PD track Operations - -Main verification circuits determine the present of
velocity target in the velocity loop.
- CWI Operation - -The carrier frequency is FM modulated by CODING and
RANGING.
- MASG - -Generates simulated Dopplar fed to the missile prior to launch.
- Fixed Feedhorn - -Beam width is 2.6 degrees wide.
- Notated Feedhorn - -Beam width is 4.4 degrees wide.
- Acquisition Condition - -Elevation and azimuth commands from the
antenna control by DIGITAL COMPUTER.
- Radar digital computer - -Performs all computations required to exercise
and control fire control. 5 basic sections.
- Control - -Provides timing and control of all computer operations based on
instructions from memory.
- Memory - -Stores data
- Arithmetic - -Performs logic functions
- Input - -Receives data from the radar and avionics subsystems. Converts it
into proper format.
- Output - -Converts data to the format for the radar and avionics
subsystems.
- Multipurpose Display Group - -Consist of 3 units and provides a means of
usually presenting radar targets return, interception, steering commands,
missile launch
