ASE Flashcards
Where is the AN/APR–39 radar warning receiver(RWR) digital processors located in the aircraft?
Left avionics bay
Which component provides radar, laser, and missile threat audio to the crewmembers?
Communication interface unit (CIU)
Where are RWR,LWR and MWS detected threats displayed on the ASE and TSD pages of the multipurpose display?
ASE threat symbols are always displayed on the inside of the ASE footprint
When will an ASE footprint be displayed on the TSD page?
When ASE threats are selected for presentation from the TSD-Threat/SHOW page and at least one threat exist for display
How may the AN/APR39A radar warning receiver (RWR) be declassified?
Remove the User Data Module (UDM)
What is the purpose of the blade antenna within the RWR system?
Receives C/D band radio, frequency, energy, and routes it to the digital processor
What indication does the AN/APR–39 RWR PROVIDE IF THE RECEIVED THREAT DETECTION DOES NOT MATCH A STORE THREAT IN THE EID file?
A “U” Will be displayed
How can the crew identify the systems number one priority ASE emitter when looking at the ASE or TSD pages?
The emitter will have a Homeplate symbol surrounding it
Which component contains a classified operational software required for tactical operation of the laser detecting set (LDS/LWR)?
The user data module (UDM)
What three threats are detected by the LDS/LWR?
Beam rider, designator, and range finder
How many degrees of detection are provided by the LDS/LWR in elevation?
+-45
How many degrees of detection are provided by the LDS/LWR in azimuth?
360
The AN/AVR–2B laser detector set is designed to operate in conjunction with which other ASE system?
APR-39 RSDS/RWR
The RFI gives the crew 360° of coverage. What numeric values define the fine area?
90°, with 45° each side of the FCR centerline
What is the primary difference between the fine and coarse areas of coverage?
Azimuth accuracy is much better than the fine area of coverage.
What three types of radar systems can RFI detect?
Pulse, Pulse Doppler, and Continuous Wave
What is a primary function of the RFI system?
It functions primarily as an offensive system that provides an FOV target cueing for onboard and offboard sites/sensors for employment of weapons.
What identifies an emitter that has been detected in the fine area of coverage of the RFI antenna array?
A triangle at the bottom center of the symbol
On what three FCR operational modes will RFI icons be displayed?
GTM, RMAP, ATM
How can you differentiate between a priority emitter that is tracking/missile guidance from another platform and an emitter that is signal, lost, lock, broken, or undetermined?
Home plate intensity
How many RFI emitters can be displayed on the FCR, ASE and TSE pages?
10
What symbology indicates an MRFI interim solution?
A line with increasing/decreasing Chevrons
What two configurations can MRFI be installed?
FCR (pinned) and URX
