6. Overview Of Array Technology And Calibration
Active Phased Arrays Feature Many Active Circuits (i.e. T/R Modules) Operating In Parallel Behind The Various Elements Both On Transmit And Receive
To Maintain Antenna Performance (i.e. Low Sidelobes and Accurate Beam Pointing), The Array Must Be Calibrated To Equalize Amplitude and Phase Variations Due To The Active Circuits
Initial Near-Field Range Calibration
Periodic In-Field Calibration
T/R Modules

8. Path to Transition Array Features
Array Features Necessary To Support Auto-Calibration Were Identified And Analysis Approach Defined With Examples. Relevant Array Features Include
Array Element Error Budget (Effects on Sidelobe Level and Beam Pointing)
A/D and LNA Linearity
Calibration Signal-to-Noise
External Echo Effects
Calibration Timing
Array Features Identified Above Flowed Directly Into The Design of the Auto-Calibration Algorithm

9. Path to Transition Modeling and Simulation Tool
The Auto-Calibration Algorithm, Array and Signal Models, And Antenna Pattern Generation Were Integrated Into A Common M&S Tool
Supports different antenna architectures
Simulate calibration signal and utilizes measured data (amp/phs measurements, attenuator/phase shifter response curves, etc.)
Generates pre and post calibrated beam patterns
M&S Tool Has Multiple Uses
Exercises algorithm under different array configurations and sizes
Refine algorithm and optimize parameters for an array under test
Support future demonstration and testing by incorporating measured data

10. Path to Transition Demonstration & Future Plans
TSC and RF Alliance Received Strong Interest From Navy To Conduct A Proof-Of-Concept Demonstration With An IWS Asset
Navy authorization was received and demonstration is expected to start in the fall
Future Plans (Pending Demonstration Results)
Development of operational software package
Tailor operational software to candidate radar system
Fully test and quantify performance
