When a single antenna is used to transmit or receive, how is damage to the receiver avoided? |
Multipactor |
|
What 2 types of signals are primarily transmitted by the APG-63 radar? |
HPRF and MPRF |
|
Radar returns yield what type of information about a target? |
presence,direction,range and velocity |
|
How is range to the target calculated? |
by measuring time between transmission and reception of a pulse |
|
If the target has a lower frequency return rate, is the target getting closer or further away? |
further away |
|
List major LRU's of APG-63 set. |
Radar C/P(541), power supply(610), RF oscillator(001), transmitter(011), receiver (022), analog processor(039), data processor(081), programmable signal processor(042), antenna(031) |
|
Which LRU generates basic RF op. freq. for radar set? |
RF oscillator (011) |
|
Which LRU amplifies low power RF (GTWT drive) from the RFO? |
transmitter (011) |
|
Receiver amplifies RF returns, converts them to 30MHz IF signals, amplifies them again, and send them to which radar component? |
Analog Processor (039) |
|
What type of commands does the data processor (081) send to the power supply (610)? |
antenna positioning commands
|
|
What does the programmable signal processor provide? |
target detection,filtering,range measurement, target parameter, clutter cancelling, IFF correlation |
|
Explain the purpose of the Flood Horn. |
tracking ability for gun, 081 can provide backup for AIM-7 guidance |
|
Which LRU receives digital data from CC and radar set, analog/discrete from radar set, and a composite video signal from PACS? |
PSDP |
|
During transmitting function, which component sends the frequency selection to the RFO? |
data processor (081) |
|
During trans. function, how does the RFO send the GTWT drive signal and to which component? |
through a waveguide to a transmitter |
|
How does the APG-63 radar set filter out ground clutter? |
guard horn |
|
The receiving function of the APG-63 is divided into what 2 categories? |
search & track |
|
Which component is the only LRU involved in the data processing function? |
data processor (081) |
|
Which LRU is the only radar component required liquid cooling? |
transmitter (011) |
|
List the five assumptions the radar BIT makes. |
single fault concept, maintenance done as indicated, replacement LRU is serviceable, operator actions correct, external interfaces are correct |
|
When running an operate IBIT on the ground, what should be displayed in the BIT window? |
G TEST |
|
During which BIT are the faults detected by the radar displayed?
|
Standby IBIT |
|
What is the purpose of the indicator group? |
display system made up of PSDP and MICP, converts analog/digital input for displays |
|
Explain HPRF ops. of the APG-63 radar set? |
provides max detection against nose targeted aspects in long range detection and tracking capability. Poor detection against tail aspect targets |
|
What detection ranges are available during only MPRF operation? |
10-80 nmi |
|
If the pilot wants to continue searching for other targets while tracking another target, he can accomplish this by using which mode group? |
Track while scan |
|
What is the primary A/A search mode and is used for detecting and acquisition of both closing and opening rate airborne targets? |
Long range search |
|
What is acquisition and how can a pilot acquire a target? |
picking out targets, manually and automatically |
|
During manual acquisition, what control is used to move the acquisition symbol around the radar display? |
TDC on right throttle grip |
