Section 4 Flashcards
Where can SAR high resolution imagery be displayed?
MFW
HUD
What components make up the Lynx SAR system?
Gimbal Antenna Assembly
Radar Electronics Assembly
GPS Receiver/Battery Backup Assembly
What are the main system control components in the GCS for the Lynx SAR?
LMA
MFW
PSO Workstations
What does the Gimbal Antenna Assembly do for the SAR?
Position based on azimuth and elevation to provide hemispherical coverage under the aircraft.
What does the Inertial Measurement Unit do for the SAR?
Provides high resolution motion data to the motion measurement software within the REA.
How long does the aircraft need to maintain straight and level flight for the radar to align properly?
40 sec if in flight
2-4 minutes and up to 12 minutes if on ground
Can banking/climbing/descending degrade SAR performance?
Yes
What does the Radar Electronics Assembly do for the SAR?
Sets sensor modes/configurations Directs the antenna Processes raw data from RX/TX Runs system tests Performs motion compensation functions Outputs imagery Receives position data Provides terrain elevation data Interfaces with the RCM
What does the GPS receiver/battery backup assembly do for the SAR?
Provides real-time position data to the REA
Bank angle should not exceed how many degrees in order to maintain satellite reception?
30 degrees
What is the software used to operate the SAR?
CLAW
What is the Air View Manager?
Term for the analog video feed from the Lynx REA
What is the Ground View Manger?
Term for the composite video feed from the lynx ground interface
What is the View Manager Interface?
User-friendly interface used with Lynx output imagery
What resolution modes are available for the SAR?
3M/1M/1FT/6IN/4IN
What is the squint angle for the SAR?
-45 - -135
+45 - +135
What functions does CLAW perform?
Capture and record radar imagery and GMTI data
Post-processing analysis of imagery
Enter/Display/Import/Export Mission plans and waypoints
What are the left/center/right areas of CLAW?
Control Region
Thumbnail Region
Main Display Region
What is the Talon Tab used for?
Imagery analysis/viewing.manipulation
What will you see if the radar cannot collect the images desired?
“Flight Dynamics Exceeded”
What is Spot Mode?
Single Image based on coordinates on the ground
Allows finer resolution than strip maps
What are Strip Maps?
Used to image large areas
Images are tiled next to each other to form continuous area coverage
Broadside only
What is Geo-Referenced Strip Map Mode?
Produces high quality change detection pairs
What is Brick Map mode?
Used to maximize the coverage of the imagery
Tiles imagery
What is GMTI used from?
Detecting ground moving targets
Doppler based system
