What are the FIVE functional areas of the radar?
|
1. Transmit
2. Antenna Drive & Stabilization 3. Receive 4. Control 5. Processing |
|
|
What components make up the Transmit Area?
|
Exciter (XCTR)
High Power Combiner (HPC) Transmitters (XMTR) |
|
|
This radar component executes radar timing signals necessary to complete the subframe and generates/provides the necessary frequencies:
|
Exciter (XCTR)
|
|
|
How many CPIs are required to resolve radial velocity ambiguities and make up one dwell?
|
5-7
|
|
|
What functions are performed by the HPC?
|
Receives pulses from XCTR, divides each one into four equal low-power pulses and sends them to XMTRs; later, it converts the four received signals into one high powered pulse string.
|
|
|
What components make up the Antenna functional area?
|
1. Antenna
2. Antenna Servo Electronics 3. IMU |
|
|
How long does it take the radar to move from side to side?
|
2 seconds
|
|
|
What does the INU provide to the antenna drive & stabilization?
|
attitude and velocity data via the RSB
|
|
|
The Antenna Servo Electronics do what?
|
drive the radar antenna positioning motors (servos)
|
|
|
What does the IMG accomplish?
|
Measures rate of movement - sends info to the ASE & RCU to drive the radar antenna in the proper direction to stabilize it and compensate for aircraft motion
|
|
|
What are the components of the RECEIVE function?
|
1. Receiver Channel Assemblies (MDC)
2. Receiver A/D Converters |
|
|
What is the purpose of the Microwave Down Converters (receiver channel assemblies)?
|
Receive returning RF signals from the antenna array and down-convert them to IF (intermediate frequency) signals via a 2-stage process.
|
|
|
What is the purpose of the 2 Receiver A/D Converters?
|
1 receiver performs primary radar target processing while the other performs other functions (see classified T.O.)
Main function is to condition IF signals for further processing by the RASPs. |
|
|
What are the components of the CONTROL function?
|
1. Radar Control Unit (RCU)
2. Radar Subsystem Lans & Buses |
|
|
What component makes up the PROCESSING function?
|
the RASPs (2)
|
|
|
What are the 3 types of swaths?
|
Inner-Inner
Inner Outer |
|
|
Dwells are laid down in serial fashion from ____ to ____.
|
aft, fore
|
|
|
A dwell is comprised of a series of _______.
|
CPIs
|
|
|
A CPI is comprised of a series of _______.
|
pulses
|
|
|
Swaths are made up of _____.
|
Dwells
|
|
|
The radar signal is comprised of what four parts?
|
Pulse
CPI Dwell Swath |
|
|
What is the most important concept a SMO needs to master?
|
Timeline Management Discipline
