Active Array Auto-Calibration RF Alliance Project Active Array Auto-Calibration W265-092 / 15 September 2011 5

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 A/D Receiver Array Elements A Practical Approach Is Needed W265-092 / 15 September 2011 6

Assessment of In-Field Calibration Techniques Characteristics Approach W265-092 / 15 September 2011 7

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 W265-092 / 15 September 2011 8

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 Auto-Cal Algorithm Simulated UnCalibrated Antenna Pattern Simulated Calibrated Antenna Pattern W265-092 / 15 September 2011 9

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 W265-092 / 15 September 2011 10
